    Re: Grub windows error

    Did you copy this to the efi partition?

    Windows UEFI install should have backup of bootmgfw.efi here:
    C:\Windows\Boot\EFI\bootmgfw.efi from a working Windows x86_64 installation.

    Copy to this file?
    /EFI/Microsoft/Boot/bootmgfw.efi

    Mount point in LInux may be different:

    /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi

    Re: Grub windows error

    Hey so I did what you suggested then ran windows startup repair off a usb (was a pain to make it UEFI) and now I can boot on windows when my second hard drive is disabled in bios. With the MBR enabled, I get the "windows is loading files" screen then the "start windows repair" or "start windows normally" screen but it is stuck in that loop. Should I simply delete the linux partitions on the MBR?

    UEFI and BIOS are not compatible, but a system can boot either one. Each writes boot info needed by operating system differently so one sytem cannot be UEFI and the other BIOS as they have to read the same info.

    If you want to dual boot, you have to go into UEFI and change to UEFI to boot Windows and change to BIOS/CSM/Legacy to boot Ubuntu the way you have installed. Only if both systems are UEFI or both BIOS will it be easy to dual boot from grub2's menu.

    Okay, anyway I just removed the two partitions from the MBR and windows booted up fine. I'm now going to try installing dualboot on the SSD. Thanks for your help!
