Thank you for sharing this info to your colleagues.
You specified that part of the video was informational although all is perfect for me.
Please specify on which part to emphasize for the exam.

[@compsecgadgets]

Glad this is helpful. Any parts that I specifically mention as informational don't worry about them in the exam.

hello im from indonesian and i love your video

[@Franchyze923]

awesome video! cleared up some confusion I had around all this. What is more common these days MBR or GPT? Seems like GPT would be since it's more modern, but I read MBR is more compatible.

[@compsecgadgets]

I still see mostly MBR and people are more concerned with compatibility.

[@atotalidiot]

you're awesome dude!

[@compsecgadgets]

thanks mate 👍

[@harrysnikolaidis1688]

Thanks a lot for the informations , but i have a problem. I can't understand what "Partition #1 contains a LVM2_member signature" means. When i try to create a new partition 1 of type 'Extended' and of size 5 GiB, then these message i wrote above its appears. If you can help me i would appreciate it. Thank you in adavance!

[@compsecgadgets]

It means that the partition must've had another use at some point. You can safely overwrite it if you know that partition is not being used.

Hey man! thanks for all the vids. I went to your Patreon page and I coudn't figure out how I can contribute

[@compsecgadgets]

Thanks a lot, really appreciate it. I ended up using KoFi as find Patreon only really offers a subscription model. ko-fi.com/csg_yt is the page if you want to contribute 👍

[@ali2538]

@@compsecgadgets Thank you. I just used it and will again. I know it's a lot of work but it might be a good idea to update the discriptions on your videos with a link to this page. and thanks again for your videos.

[@coyotetre185]

Tried to support you through patron, but couldn't figure out how.

[@compsecgadgets]

Tried Patreon and found it really hard to work with and they were looking for a subscription model which didn't fit. Thanks for your interest in supporting! I use ko-fi now: ko-fi.com/csg_yt/
