    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!

    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.

    How to make Windows 10 bootloader As default bootloader

    If you're using UEFI, you might have to use that to edit.
    Modified from here:
    How to set Windows bootloader as default bootloader?
    To repair your Windows bootloader, if you have a Windows CD

    1. Boot from CD
    2. From title screen, open terminal (the button is usually in bottom left corner)
    3. Execute bootrec /fixmbr

      If this doesn't give desired results, try bootrec /fixboot
