    Disable EFI bootloader Windows 10

    Hello and thank you for your answer. I disabled the Hibernation as you said (now i don't have the 'Turn on fast startup (Recommended)' inside Power Options), but after a restart, nothing changes, still boots into Windows 10. From what i've read i think the EFI detects another bootloader at startup and deletes it (Linux's grub2), because normally, after Ubuntu's installation it should boot directly into grub2 bootloader (i attached a picture). I'm using EasyBCD usually to repair the Windows Metro bootloader (picture attached - it should look just like the screenshot) to chose from it which OS i want to use.

    Disable EFI bootloader Windows 10

    I managed to solve the problem on askUbuntu forum. Basically, the Acer systems requires some additional steps inside BIOS (to mark "trust" the Ubuntu's EFI files and set them as 1st option as boot option), for enabling Ubuntu's Grub2 bootloader to start before Windows 10. Now everything works. I don't have to use EasyBCD inside Windows 10. Have a great weekend everyone!

    Windows 10 USB boot

    Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

    System wont boot, trying to repair via win 10 usb installer.

    Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

    So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
    If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

    There is three options:
    Windows 10
    Windows 10 Home
    Windows 10 N

    Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

    System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

    Also is there any other software I can load onto the usb that can repair the bootloader easily?
    That would be the ideal alternative. Thanks
