    Wow Brother, you saved my day. I bought an Acer Intel PC and this UEFI interface appeared and I hardly found anything on the Internet to start booting from USB to install windows. I am really grateful. Thank you very much! I followed your explanations and it worked perfectly. 😊

    I have a problem, the bcfg command is missing. I have an EFI shell version 2.70 [5.19]. What can I do to get Windows to start right away, and not EFI???

  • @ScottHarvey-x7d
    @ScottHarvey-x7d Рік тому +2

    This was an honest presentation of this subject, funny too. I wanted to lean more about the EFI shell, for example, in linux my root drive has a different partuuid in the EFI shell, than the same root drive has after the system has fully booted up. For boot I need to find out the partuuid is in EFI. Thank you for your EFI video.

    This was great, thanks!
    Another useful trick is to add "page=#" to the end of your command, it will add pagination. The # you enter will be the number of lines you want per page. Sometimes you end up with really long output and the buffer isn't big enough to display it all, this will allow you to page through the info (like the "more" and "less" Linux commands)

    So far this has been the most useful video I've found, but i don't see any executables. I'm trying to get past the EFI menu, windows won't boot up so this is as far i can get. The MSI BIOS menu doesn't seem to have anything useful for my situation.
    Been messing about on and off for two years with this thing, my only achievement is getting rid of a black startup screen, so i do got access to the BIOS and the EFI menu, i just don't know what to do from here.

    • @EXITZER0
      @EXITZER0  2 роки тому +1

      if there is no EFI executables, it's either you don't have a bootloader (accidentally removed) or it's a legacy OS install (MBR).
      The easiest solution would be to move your important data out and do a fresh OS install.
