    An easier method to get win boot manager to work in the UEFI boot sources.


    Go there.right click on extract all and run DualBootRepair.exe. then select automatic repair bottom left.

    So I did exactly like you said, I extracted all then I ran DualBootRepair.exe. Then I clicked automatic repair. It said it was successful, but after restarting my computer, grub still popped up.

    Hi there, @cameron121901. When you speak of a BIOS boot menu, are you speaking of something similar to the center of this pic? Answer this and we shall go from there.

    Anywho, do the diskpart portion as topgundcp stated here to remove traces of the grub menu:

    diskpart
    select disk 0
    select partition 1
    format fs=fat32 quick
    exit

    Instead of using Macrium, use Option Five of this tutorial to repair:

    Iíve tried creating a windows boot usb, but the program windows gives me to make one only allows me to use a Windows 10 ISO. I have Windows 10 Home Edition.

    And yeah, that BIOS is similar I guess, but Windows Boot Manager is no longer there.

    Sorry to see that for you. I figured it was a limitation with the Home edition, but worth a try. Unless someone can comes up with something else, I'm afraid you'll have to clean install. Seems that you're an advanced user, but I can only hope that you backed up important files.

    The Media Creation Tool will create a Windows 10 ISO file that contains multiple versions of Windows 10, including Windows 10 Home. What has happened to your system is that the Linux boot loader has taken over the EFI System Partition. You need to delete the EFI System Partition, recreate it, then use the bcdboot command to write the Windows 10 boot loader back to the new EFI System Partition.

    Sounds good. Could you give me something step by step though? I think that would work then, and make me more comfortable.
