Windows 10 Wont Boot, How To Fix Master Boot Record
Вставка
- Опубліковано 2 жов 2024
- A few weeks ago I showed you how to fix a UEFI boot loader. Today we are going to fix an MBR boot loader. a master boot record partition as it turns out is a lot harder to fix then a GPT partition. But harder doesn't mean its impossible. I'll show you how to do it in this video.

#Windows #Broken #Tech
Thx for teaching an old dog a new trick. Usually when the /bootfix fails on me, I assume it's because the OS is just beyond repair. Now that I know it's because of 1703, that's a game changer for me! We can collab ANY time you want, brother! 👍💪
I wasn't aware of what was causing the problem ether until I did the research for this video. Many guides would mention the 1703 issue but were never clear on it. It wasn't until I tried it on a 1703 disk that it worked. The video almost didn't get made because of it.
Hello Rich, I can't tell ya how much I appreciate this awesome video. Early July of this year (2024) we had a lightning strike that took out 3 routers, 2 computers and a UPS. After almost 2 months of waiting on replacement parts (2 motherboards, new memory) I'm finally getting things up and running again.
I haven't tried the repair solution you shared in this video, however it looks extremely promising and will actually work.
Hopefully I wouldn't need direct help from you, if I did happen to need a little extra guidance would you be willing to answer my questions and assist me?
Hopefully I can manage to hold my mouth right as I'm performing the steps you have shared in this video. In a brief explanation the system I am working on is mom's computer and it is a dual boot (Windows XP Pro 32 bit and Windows 10 Home 64 bit) there are 2 hard drives, each drive is a terabyte in size and each drive has 2 partitions split as closely as possible to 500 GB per partition on each drive. A recent discovery was the XP is on one of the drives and 10 on the other drive.
I didn't intend to do that as I intended both OSs to be on one drive and the other drive would be exclusive for storage.
Anyway I have a slight concern that the dual boot as described could cause the operation of repairing the BOOTMGR to fail. Anyway thanks for taking the time to read my post 😃😄.
The only (little) problem I had following your video is that BCD appeared to be read only and hidden. But after solving that: it worked, great man, thank you very much !
How to solve read only and hidden BCD
@@TiaguinhoMu by means of the attrib command
Out of date!
You don't need fixboot, fixmbr or indeed bootrec at all!
It's far easier than you think.
Delete the useless start partition with your favorite Partition tool.
To create with DISKPART at the beginning of the drive:
create part primary size=80 offset=1
Then:
Format quick fs=NTFS label=system
assign (gives a letter)
Then very important:
ACTIVE
list vol (take note of windows and system partition letters, for this example system is G:)
Exit
Then:
Bcdboot F:\windows /S G:
(Sets up all the boot files)
Exit
Reboot
Easy?

Please @armsby can I contact you so you can give some tips? Because mine isn't working 😢
Sure, give me a contact address Muhammad. Any bootable Win10 or Win11 ISO will do it without looking for an old version. @@MuhammadShamsudeenSuleiman2467

Thank you, thank you!!! You just helped me fix my parents ancient laptop. Somehow the hidden boot drive switched to D. But I followed your instructions and luckily had an ancient Win7 boot cd, and it now boots up. Thanks so much!!!
I love this guy's tutorials man. I haven't used Windows in years as a daily driver and if I get such errors I'll simply revert to a clean snapshot for my VM, but this guy simply has the type of energy for a UA-camr that you want to watch his videos even if you'll never have to resolve such problems.
(maybe handy to recommend for a friend though!)
This was an absolute life saver. I installed a new psu with the wrong cables and something happened to my ssd so that it couldn’t boot anymore. Just went straight to bios. I spent nearly 10 hours troubleshooting and testing components before I found this video. My boot files must have been corrupted somehow and this fixed them. Can’t thank you enough.
You were lucky your SSD only had issues...
I cannot emphasize how useful this video is. Thank you so much.
This particular video will end up in my Watch later playlist, cause I'm gonna use it at some point in the future.
You are a genius! I can not thank you enough for saving my drive. I will definitely make an image of my OS,
Its such a relief to be back in my accounts and I want to send big love from germany.
The 1703 build just magically did it. Insane.
Thank you brother, my system had a problem, with this video of yours, my problem was solved, I am from Iran, thank you for everything
Or here's another scenario your computer gets hacked the hacker finds your MBR file and deletes it! And if that happens when you log off your computer and when you go to log back in your computer you will either be directed to your bios or your windows advanced settings menu. At that point it's a total shit show from there but it will definitely build up your knowledge and education within computing and IT.
I literally think this exact thing happened to me, did this happen to you and if so how did you fix it?
@@vampg4ze Yes! Its called hence the name "LOGO-FAIL" Malware. It attachés malware straight into your "BIOS FOLDER" so when you start up your computer you get hit right away. simply because the first folder picked up on start up is your "BIOS DIR /FOLDER" And your "LOGO-FOLDER"

#1-("If you have a windows restore point folder created you go in advanced settings and go into "RECOVERY FOLDER" and RESTORE POINT and if their is a restore folder it will pop up and you select the folder and restore it from that restore point.
#2-(" Try windows repair and run the windows repair and if you get a ERROR message try it aging sometimes it takes 2 or 3 times but if it exceeds over 3 times your computer is a litter bit more corrupt then you think it is and then that will bring you to step number three!
#3-(Your computer has a serious malware problem and now the only way to 100% fix it at this point will be to INSTALL A NEW "OS SYSTEM" BECOUSE ONE OF YOUR 3 MILLION LINES OF CODING THATS IN ANY AVERAGE OS SYSTEM IS MISSING OR CORRUPTED EITHER WAY YOU LOOK AT THE SENIREO YOUR IN A BAD SPOT AND HOPEFULLY YOU DID A SECONDARY BACK UP OF YOUR
(note) - The number of lines of code in an average operating system (OS) can vary significantly based on its complexity and the specific OS in question. Let’s explore some examples:
1-Windows 10:
The fundamental components of Windows 10, including memory and processor administration, are managed by the Windows 10 kernel.
The kernel of Windows 10 is estimated to consist of approximately 3 million lines of code1.
This includes both code developed by Microsoft and code contributed by external developers.
2-Mac OS X (Apple’s operating system):
Mac OS X contains an impressive 86 million lines of code2.
Most of these lines are programmed in C and assembler, which are less tidy but more efficient languages.
-(Other notable examples ARE)
3-Google Chrome (browser) runs on approximately 6.7 million lines of code (upper estimate)3.
4-The Android operating system runs on 12-15 million lines3.
The Large Hadron Collider (LHC) uses 50 million lines3.
5-Facebook’s codebase (excluding backend code) Comprises 62 million lines3.
-Now Remember, a million lines of code, if printed, would span about 18,000 pages of text, which is more than what was needed to run old technologies like the Space Shuttle or even the game engine of Quake
- However, modern software used in everyday life today often requires much more code to function effectively. 🖥💻
Keep in mind that these numbers represent the complexity and scale of different systems, and the actual lines of code can vary based on specific implementations and optimizations.
-Now lets dive in to how all of this happens in the first Let’s delve into the intriguing world of cybersecurity and explore the notorious vulnerabilities you’ve mentioned: LogoFAIL, EternalBlue, Blue Latern, and Pegasus malware.
-1. EternalBlue: The Windows Catastrophe
EternalBlue is a software vulnerability that shook the digital landscape. Here’s what you need to know:
Origin: Discovered by the United States National Security Agency (NSA), it was part of their secret toolkit.
Target: EternalBlue exploits the Windows Server Message Block (SMB) protocol, which facilitates shared access to files, printers, and resources within a network.
Exploit Mechanism: By manipulating specially crafted packets, an attacker can execute arbitrary code on a vulnerable Windows system.
DoublePulsar: EternalBlue’s sinister companion, DoublePulsar, acts as a backdoor implant tool. Once EternalBlue opens the door, DoublePulsar injects and runs malicious code on the target system.
Lack of Segmentation: The flaw allows lateral movement within a network, enabling malware to spread from one system to another.
Why Was It So Critical?
Windows Popularity: With Windows being ubiquitous, the vulnerability put countless systems at risk.
Patch Challenges: Despite Microsoft releasing patches, many organizations lagged in implementing them or used unsupported Windows versions.
Weaponized Nature: Originally designed for espionage, EternalBlue’s sophistication made it a potent tool.
-2. LogoFAIL: Stealthy Exploitation
LogoFAIL takes a different route:
Bypassing Security Measures: This exploit cunningly evades hardware and software security solutions implemented by CPUs, operating systems, and third-party security software.
Nearly Impossible to Detect or Remove: Unlike flashy attacks, LogoFAIL operates silently, making it a nightmare for defenders.
3. Blue Latern: A Mysterious Mention
Unfortunately, I couldn’t find specific details about Blue Latern. It seems to be elusive, lurking in the shadows of the cyber realm. If you have more context, feel free to share!
-4. Pegasus: The Spyware of Nightmares
Pegasus is a notorious spyware developed by the Israeli firm NSO Group. Here’s its dark tale:
Capabilities: Pegasus infiltrates smartphones, gaining access to calls, messages, emails, and even activating the camera and microphone.
Targets: Governments and intelligence agencies deploy Pegasus for surveillance, often against journalists, activists, and dissidents.
Zero-Click Attacks: Pegasus can infect devices without any user interaction-simply receiving a malicious message triggers the exploit.
In summary, these vulnerabilities and malware exemplify the perpetual cat-and-mouse game between cybersecurity experts and threat actors. As technology evolves, so do the risks. Vigilance, timely patching, and robust defenses remain our best allies in this digital battleground.

I honestly think that this is the issue that I have with my laptop rn. I downloaded an ai software for statistics and deleted it since it's really useless then this circus happened
If I had MILLION$ to give you, it would be yours!!!! Holy cats!! I was dead in the water and you resurrected me!! 🙂 I knew what the problem was...just had to figure out a way to resolve it. This video was PHENOMENAL!!! Luckily my Windows installation CD is pre 1703, so I didn't have to fight that issue. I did, however, have to side track a little off your video and find a fix for an "Element Not Found" error when running BOOTREC /FIXBOOT. But once that issue was resolved, everything launched with success exactly as you demonstrated in your video. Just friggin' YUUUUUUUGE KUDOS to you!!!!! Thank you ~
Glad it helped.
same. Had to mark the partition as active and it worked.
I deleted bootmgr and I trying command and it doesn't copied of me. I'm reinstalling Windows
PROBLEM SOLVED: For those how need to Dual Boot with Windows 10 Pro and Windows XP in the event that Win 10 is the first one installed and XP is the second one though should be done the other way around: boot firstly in Win 10, install EasyBCD 2.4 and with its help you must insert the Win XP's boot loader in the same one of Win 10s. Hence, afterwards you should be able to have the choosing menu of opting which OS to boot from. Should anyone needs more details on that, revert here and say it!😉😉😉
Did this successfully and the efi vid. Everything is there as it should be, EFI won't boot. (no file system) (not true). Vid works just fine. There is just one last thing I can't get.
Did u fix it?
@@matvei2978 No, the bios needs to see the file system, to point to the right place. It says 'no file' system in bios for efi. Dont know how to fix that. (It is there).
Thank you so much for this info. Your delivery and content is clean and precise. Explanation of each command cuts down the wall of text I would had to read to truly understand what each command does.
I want you to grow as big as other prominent UA-camrs because your solutions respect the viewer’s time. Take care.
I just can't help myself: you're way better than Carey Holzman though he's older than you and it supposed to have much more experience than you! He's just waisting particularly our time by showing stupid tutorials rather by teaching his audience such needed issues! Well done to you once again! I do really appreciate you and all your work here on your channel!😊
Hey...great tutorials. But I have another problem that you haven't addressed. I have a Win10 install that doesn't have any other partitions other than the main windows. In other words, there is no boot partition or recovery partition on it. How can I fix it so it will boot? Thank you.

@@hunter7777 I meant a comment to this video. It starts 'Out of Date'. Search and you'll find it.
It maybe a bit too quick for some. Perhaps I'll do a real video on Boot repair on mbr.
Thanks so much for the video! In my case, I have a dual boot Windows 10/Linux Mint system. While trying to upgrade to Mint v22, GRUB got corrupted. I then removed Mint and GRUB, leaving only Windows 10. But that apparently messed up the MBR. I followed your instructions, but when I reached the bootrec /fixboot command, I got "Element Not Found" error. It turned out that my Windows boot partition wasn't active. So I used your last instruction (diskpart> active) to set it. After that, bootrec /fixboot completed successfully. Following the rest of your instructions, Windows was able to boot!
Will try it tomorrow, thanks for your input
10:42 how do I boot into recovery mbr?
The access denied bit was driving me nuts. Appreciate the ver dependency information. There are tons of write-ups out there indicating that access denied issue is fixable via other commands, but it is not.
This thing is horrible and about to reinstall. I’ve been at it all weekend. I’m frigging tired
@@whoisradu I'm at it right now... It's CRAZINESS!!
I messed up a Linux installation on a drive that I didn't know was MBR. This saved my windows installation, thanks.
Thank you for saving my life. I do something different way to save my Windows because i have slightly different case.
*1.* I have 1 disk running Windows (labeled NVME1 {C:\}) and then i install another Windows on new disk (labeled NVME2 {F:\}). After that, everytime reboot Windows giving me 2 option boot : NVME1 and NVME2
*2.* I remove all partition on NVME1 and because i want to use it as data disk, but not boot disk.
*3.* After step 2 i got boot error because system can't find booting disk.
*Solution :* i follow some of your instruction
0. Plug my Windows 10 flashdisk (H:\) and boot it, choose repair my windows, choose command prompt
1. Go to boot disk {NVME2}, select vol, set *active* volume using Diskpart
2. Copy all files in directory */boot* in my _flashdisk_ to installation disk {NVME2} using copy command (copy H:\boot\*.* F:\)
now after i have standard BCD file, i execute
3. F:\bootrec /rebuildbcd
4. F:\bootrec /fixmbr
5. F:\bootrec /fixboot
6. restart, and Windows will automate rebuild and check sistem after login
Hey there. Facing an issue w/ my pc I bought a few months back. Randomly began having a booting issue after not being able to detect my WiFi adapter. I switched over to a WiFi cable hoping it’d fix the problem and in fact made it worse. My pc will no longer boot up. I’m getting error message CRITCAL PROCESSED DIED. I went through a series of UA-cam videos and I finally came upon your page. PLEASE help if you can I’m getting gray hairs. 😭
Do an in place upgrade with the media creation tool, if you can boot to USB from your BIOS.
Thank you, it was actually MBR2GPT that borked my system, the OEM probably had some funky partitions that the tool couldn't handle.
I had to remove those and rebuild the MBR manually like you explained.
Let's hope I can upgrade it at some point...
As the tech of the company, it’s always cool to keep up with the latest tactics to deal with surprising issues like this….(that rear their ugly heads when you least expect or want them)

Great video yet again, the 1703 ver thing I didn't know about but I do remember thinking why did all the cmds work before on older win 10 installs but not anymore? Now we know about 1703 ver isos and older disks! I thought I was losing my touch.😂
@cyberCPu : it is showing element not found in bootrec /fixboot
Thank you so much! This helped me a lot. I was always wondering why every time I tried to execute "bootrec /fixboot" it gave me the "Access denied" message when repairing customers' computers. I had to use different third party software to do it, just because almost every guide out there is outdated.
I've had this issue for a long time too. I wasn't aware of the problem until I did the research for this video.
Thats is true,however i use a dedicated software for jobs like this 99% of the time because,heck they are much faster and easier than messing with the command line.
@@dimitrismaster what software do you use?
@@CyberCPU Lazesoft recovery suite(the paid version) is currently my favorite,also the rescatoux recovery(its a gui linux iso) and many others inside the "medicat usb" will fix most issues.Have a look at Medicat usb, and see if its worth making a video about it.
Here is the thing: on 16:41 minute it shows that return figure "1", but to me it returned "0", and even so, I continued your indications further more to the end and interestingly enough I still was able to boot again my laptop in Windows 10! Strange or what?! However since I've got Windows 10 on "C" partition and Win XP on other partition - though it should've been on "C" one since the right order of installation should be first Windows XP, necessarily on "C" drive and then any OS(Win 7, Win 10, Win 11 etc) on any other partition - can you please guide me how would I be able to or what and how should I do to see both operating systems and so to be able to choose which one to start with/to booth with?! So far I just can't see that menu to choose from either Win 10 or Win XP and it's booting default in Win 10. Kindly awaiting for your professional reply.
After you broken the MBR, the option "Continue to Windows 10" has disappeared from the Recovery menu leaving only Troubleshoot and Turn Off. And it returned once you fixed it 😅 so simply to find out, it won't boot again (once you broken it)
A great guide but in my case I got dead CMOS battery on my laptop and so I could no longer boot my system with GPT and EFI without changing the default setting every time, so I decided to go back to MBR. For that you have to remove any partition that is related to boot and keep only Windows partition itself, then in diskpart creat par prim, format fs=ntfs, assign letter (whatever you like), active. Afterwards use the command "bootsect /nt60 your letter of choice: /mbr" and then "bcdboot D:\windows /s C:" as follows in this video guide. After that I did fixmbr and fixboot just in case, still haven't fixed the fact that scanos can't find any system but finally my system booted up just fine.
Great tutorial. There's a bunch of half-ass Windows help channels on UA-cam, but this is not one of them.
I can’t figure this out for the life of me
Where are you getting stuck?
I let Windows 11 Update from 23H2 to 24H2 on unsupported hardware (LGA1366, Intel X58).
After that, Windows 11 then decided to break the bootmgr on it's own and refused to boot into 24H2.
It just gave me the good old "BOOTMGR Image is corrupt. The system cannot boot." error instead.
(i guess this is Microsoft's way of keeping unsupported hardware away from 24H2 lol).
Despite what you said, i had to purposely break/delete the boot folder and bootmgr to fix it
(step two alone did not work, so breaking the boot loader on purpose was the only way).
I am now finally able to boot back into my Windows 11 PC again (albeit that it went back to 23H2).
So i'd like to say thank you so much for this video, as it really saved the day for me.
Mine was a bit different problem but this helped!
Thank you!
For anyone else who stumbles upon this
My issue was that my system wouldnt take the win 10 bootable drive in either uefi or legacy mode
For UEFI to work, it needs a fat32 bootable drive
And latest Win 10 ISOs have files bigger than 4 gb
But fat32 cant have files bigger than 4 gb
thus rufus would force the drive into ntfs format
thus stopping a UEFI boot
Win 10 1703 works because the biggest file in it "install.wim" is smaller than 4 gb
therefore it can have the fat32 format
thus it can boot in UEFI mode
Im not really sure what stopped me booting it in mbr legacy mode tho
the medicat tools way easier
What is medicat tools
Holy Smokes ! ISO Version 1703 was released in 2017 ! Not many folks have access to that version. MS Support doesn't offer it either. I'll need to check through my CD Library. However is there another way to get around the Access Denied error ?
Nope, that's the only way.
You can use this to get 1703.

Hi Rich, unfortunately when running the command bootrec /rebuildbcd, I press Y, and the return line is “The requested system device cannot be found.” I am going to lose my mind!!!! Please let me know if you have a fix for this.
Man I love ! awesome tutorials you are sharing ! keep it up !
all i did was accidentally reset my pc when it had an update installing..
i was working on something and i realized i didnt have a usb port plugged in that i needed, i reached around my computer to plug it in and when i did i had accidentally hit the power button on the tower. the screen went black and so i instinctively hit the power button to turn it back on and when i did i noticed that my computer had started an update and was at 2% already by the time i reached over to hit the button again. i got a bad pool caller error code, someone suggested i update my bios which i did and no i have an inaccessible boot device error and my command prompt WILL NOT register that i even have a valid windows 10 key. all this over accidentally hitting a damn button? is there anything i can do to fix this? i have a flash drive with a windows 10 boot on it but my problem PC will not accept it, all it says is that the computer cannot repair or accept the boot file.
Thanks for posting all this. Even as a technical person, what this tells us is that windows is inordinately complex and for no good reason. My daughter's win 10 disk just gave up and fortunately before it died, I managed to clone it. So to avoid all this horrendous boot nightmare, that's what I recommend - buy another disk of the same size and clone your OS. Microsoft will probably say that's an infringement of the license agreement, but I play fair - the clone goes in my desk drawer until I need it. For those who might complain that this method requires the purchase of another disk, my answer, from my experience of Windows disk failures, is that you're going to need one to replace the failed drive, AND its much harder to reconfigure your new disk when the old one fails. Happy disk drives :) :)
you are a saver. The way you cover all the 'what if' is very essential. Thank you
I get a blue screen after trying to install some Audio software... Would this help to recovery the system? Thanks, I tried all the standard options by the way and using a windows repair was not working for me.
I had a new m.2 gen 5 that i installed win 11 on. My old drive still had windows installed. The new drive was 1tb the old drive was 2 tb, so it's idiot proof what drive needed formatted.
I used windows installation to access the hidden partitions and erased all of them for disk 1, disk 0 was my new disk and all partitions un touched. I restarted and no bootible media found. How does formatting one drive effect a completely separate drive????
bootsect command can easily fix the bootrec error without using that version of the ISO
did you try it out?
I've never found another way around the problem. I will happily look at other methods though if you know of any.

bootsect can be helpful in that recreating mbr sector before fixing the boot record. you can get help with:

Just make sure to choose /nt60 because /nt52 for Windows XP and below.

Thank you. I should have followed your instructions here (for broken MBR) but I followed the ones given for broken UEFI, first.
In the process, I discovered that my partition is MBR, as when I tried to install Windows ... I got an error saying - "Windows cannot be installed to this disk, as it has a MBR partition table On EFI systems Windows can only be installed on GPT disks"
So a natural question - how should I have determined what I needed beforehand.
just saved my u know what man! i used a tool to convert my m2 drive from mbr to gpt and that is when all hell rained down on me. My ASUS bios was freaking out and doing some crazy things. I still need to upgrade to WIN 11 and that is why i tried to convert to gpt. Need a new plan to upgrade and keep all have already. Would buying another m2 drive and converting it to gpt before cloning over from the old m2 drive work? I assume not. Hmm THANK YOU !!

Hi bro I enabled secure boot on my gigabyte b450 ds3h and when saved and exited it showed a black screen and nothing is booting now. I have tried every thing there is from cmos removing to removing RAM , removing gpu but nothing is working. I have an amd ryzen 3 3100 with igpu so i cant boot using the motherboard. Please help me with anything you know.
My WIN10 crashed BUT the boot drive came back as RAW. And WIN made my former C:> D:> and D:> C:> per DISKPART.
I removed the drive and connected it to an SSD-to-USB able and plugged it into a working PC and looked at the crashed drive in Disk Manager. Disk Manager sees the drive and it looks like it has four partitions, left to right, 100 MB Healthy EFI System Partition; 235GB RAW Healthy Basic DATA Partition; 515MB Healthy Recovery Partition; 1MB Unallocated.
How can I repair or at minimum convert RAW to NTFS without losing files so I can recover some files/directories?
It used to be "fdisk /mbr"

Everything worked until I did the bootrec /rebuildbcd and then after hitting y it returned "the requested system device cannot be found"
Dude, I shouldn't been throwing that CD like that 😂, I convert mbr to gpt unfortunately the boot disappeared now i had a drive without a bootable wish I had that cd
Well, although for the step at 16:50 I get an error that the drive or so could not be found and then I exited, after reboot the system booted into Windows suddenly. So, thank you very much!
Very good info thanks!
Please do a tutorial on double boot systems.
Just did a Windows update and the PC won't boot anymore... Microsoft sucks.
does it work if windows has startup repair loop?
Hey mate,
I don't know who to ask but you.
Occasionally I get a BSOD ( Power State Failure ) it happens when I wake my computer from sleep.
I have my power settings on High performance also My drivers up to date
Would you happen to know a fix for this or anything I could try?
I did find a command on a YT video I could try but Im not really sure what it does maybe you could tell me? REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"
Thanks
I get access denied and i am using an older version of w10, i do not have a bcd file. I see windows in my dir. but it is never found when attempting to rebuild bcd.
work but in 21h iso 😂 and actually it give me access denied but i just skiped this step and it just work 😂
Thank you for the detailed explanation and steps to recover the MBR.
Amazing. I learned computers after DOS so all this stuff is fairly new to me but I did not want to reinstall windows again. I'm having issues with my oc lately and long story short I reinstalled windows in a new SSD and at boot up I have to always select which disk to use. Yesterday tried deleting the old drive and that's it...I could not get back in for the life of me. I followed your instructions and was able to fix the disk and get in. Thanks.
You can just type in wpeutil reboot instead of exiting
These videos are great but I can't even get into the usb boot media without the system crashing..
Thanks man, that actually helped even though I didnt passed the bcd rename procedure as my bcd files where hidden and I couldnt rename it. But doing futher steps helped win10 boot system to see the win installation and boot the pc eventualy) Windows was copied with Partition minitool Just as is No transfer functuon or aomething
So cool. This helped a lot
Glad it helped.
@@CyberCPU I was wondering how do you screen record in recovery mode?
@@Warmachine-fortnite I have a device that record's the HDMI output of my system too a USB thumb drive. I typically use it as just a backup recording but in cases like recovery, it's my primary recording device.
u a life saver man, i done messed up my dad's shit, i would've been in huge trouble😂
To resolve issues with the Master Boot Record (MBR) in Windows, you can follow these steps:
1. Use Windows Automatic Repair:
- Boot your Windows system and enter Automatic Repair mode.
- Select Advanced options > Troubleshoot > Startup Repair.
2. Use Command Prompt:
- Create a Windows 10 USB bootable media.
- Launch Command Prompt and run the following commands:
- bootrec /RebuildBcd
- bootrec /fixMbr
- bootrec /fixboot
3. Repair MBR on BIOS systems with MBR-partitioned drives:
- Launch Command Prompt and run:
- bootrec /FixMbr
- bootrec /FixBoot
These steps should help you repair and fix any issues with the Master Boot Record on your Windows system.
Your instructions are out of date!
The "bootrec /fixboot" command can no longer be used for boot repair, because the command always shows "Access is denied". Microsoft has prevented the use of the "bootrec /fixboot" command on both GPT and MBR disks.
Windows 10 version 1703 (April 5, 2017) and earlier installation media.
- bootrec /fixboot -> "The operation completed successfully"
Windows 11 and Windows 10 version 1709 (October 17, 2017) and newer installation media.
- bootrec /fixboot -> "Access is denied"
==============================
You don't need the "bootrec /fixboot" and "bootrec /rebuildbcd" commands if you use the BCDBOOT command.
BCDBOOT [/s [/f ]]
If the system partition has been corrupted, you can use BCDBOOT to recreate the system partition files. BCDBOOT copies the boot files from the Windows partition to the system partition and creates the Boot Configuration Data (BCD) store in the same partition.
The BCDBOOT command works on both GPT and MBR disks.
==============================
I thought my computer was completely borked when it wouldn't boot passed bios, but thankfully I found this and it booted up afterwards!
Excellent, you helped my restore my system. Thanks.
Thanks Rich! I was about to give up on trying to restore an HP Compaq Pro 6305 Small Form Factor using a "repair cd" when I came across this video. Even though I didn't fully understand the logic of all the commands, I did what your said to do here, brought it back, and it boots up fine now. I am not savvy on how to "Run an older ISO," but when you instructed us to put c:>bootrec /scanos it said "Total Identified Windows Installations:0" YOU then pointed out the BCD file at the top of the list. Well my list didn't have a BCD file there but I just continued following your instructions as if it did, and renamed BCD (a file NOT ON THE LIST, and I didn't delete/break it as you did "on purpose for your video"): But I did this rename anyway expecting it to fail since I was renaming something not there... I entered: c:\Boot>ren BCD BCD.bk and got no error message, but unfortunately, I didn't check to see if BCD or BCD.BK was there now or not. I did the c:>bootrec /fixmbr and it said "Completed successfully." When I did c:\>bootrec /fixboot, it said "Access Denied" like you said it might I just followed you and continued rebuilding the BCD. Even though I had these different things happen during this process, bottom line the PC is running great, so it must have rebuilt all it needed! I was in telecom for many years and have never seen such tremendous support as you have given here...Extremely Impressed Thx again...
Why MBR?
I have windows and disk instalednin GPT partitions and disk?
Fail...BUT, let me explain. I followed all of your directions and it didn't work. Then, I went back and watched the video again. It was GREAT that you mentioned that you must boot your flash drive up in MBR and not UEFI if you're fixing MBR. That was the game changer!!! BUT, after I went thru all of the steps, instead of resulting in successfully completed when answering Y to assign the windows installation to the MBR, I got the response: "The requested system device cannot be found" ... Ughhhh. Now what? Answer: In my case, nothing. Because (I think) the MBR had the windows installation by default as C:\windows...so I just ended up rebooting after taking the flash drive out. If my windows install was on another partition, I don't know what would have happened. Resulting boot time? 317 seconds to get back into windows. lol .... Thank you! Thank you! Thank you! You are the man!!
I was dual booting my Windows 10 laptop with primeos and without using a USB or a Cd using steps told by an Indian youtuber and now my laptop won't open. It's stuck at a blue screen that says BAD SYSTEM CONFIG INFO and I tried to fix it with cmd troubleshooting told by another UA-camr and it doesn't work.. It's a cry for help. Please help
Does the system crave curry? Did u try accessing files using a live Linux distro
Yo, guys! I did mistake when transformed my MBR disk to GPT... Then I walked around this shit around 2 days... Then I understood one simple thing - to do through MiniPartitionTool partition that had windows boot inside Active again... And... Now Im doing back-up of my Win11 Pro with MBR structure(whole disk) to do smarter convert of MBR to GPT again. Now I will do my laptop faster loading XD 1 minute is quite time.
Where is this ventoy link ??? (I am watching this video from my mobile phone for the obvious reason that my PC windows 10 are broken) And Ventoy link is NOT in description below!!! (Only a t-shirt merchandise link and sponsor link's to buy windows 10 and windows 11 and MS office keys)! So where is the ventoy link ???
On my end it says add installation to the boot list system device cannot be found
(Solved it still worked)
Thank you. I've been banging my head trying to get Windows 10 to boot again for the past few weeks. I got sick of Windows 10 corrupting my media drives, tried to switch to Linux, but it refused to mount the drives until WIndows had marked them clean.
Now I've finally got Widnows 10 running and ran chkdsk on all of them. Time for Linux install.
Help me to fix this please, am trying to activate my windows 11 pro. This what it's saying.."We can't activate windows on this device as we can't connect to your organization activation server. make sure you are connected to you're organization's network and try again."
Sounds like someone tried to bypass activation. I know it's possible to fix but you have to reset all your activation settings. I can't recall how to do it. It's been a while since I've had too.
@@CyberCPU So.. 1) I have to remove product key from windows. 2) Remove product key from registry, so that I can reset windows activation
@@Kijana_Kenya_Official it's been a long time since I've seen the issue. It's typically associated with someone trying to bypass activation with a crack of some kind. I don't remember how to fix it. It's been at least a couple years since I've had to do it.
Wow, being a guy who has been using bootable floppy for windows 95 this was a wow effect to fix a MBR, and i have been formatting my windows drive like stupid once the system was not booting up. Thank you so very much. Really appreciated. You just got yourself another student. 🎉😅😊
Can a machine that has broken MBR be made to boot using GPT type disk?
Another question I have>
Can a machine that has only BIOS no UEFI boot anymore? My i7-4770s don't have any UEFI. They boot. I should check and see what the disk type is. I think they are GPT but shouldn't have EFI partition.
I went through the process of fixmbr and fixboot successfully for my drive, but diskpart wont let me set the drive as active. Gives the error that “active” can only be used on “fixed mbr disks.” Did I not just fixmbr on that drive?? I don’t understand
Also I got to 16:56 but I got “The requested system device cannot be found”
Yes!Yes!Yes! It worked! Haha! What happened in my case is my PC was doing a system update and the mbr failed. I had tried three other UA-cam tutorials with no luck. I did, however, have a newer USB installation file, and I had to make a couple of skips, but it worked. Now, you should make a video on exactly what to do after recovering from a catastrophic scenario to lessen the chances of it happening again.
