    Re: Can't boot to Windows

    Both of these entries should work. Not sure why they think it is recovery.

    menuentry "Windows UEFI recovery bootmgfw.efi" {
    search --fs-uuid --no-floppy --set=root 6CFD-C181
    chainloader (${root})/EFI/Microsoft/Boot/bootmgfw.efi
    }

    menuentry "Windows Boot UEFI recovery" {
    search --fs-uuid --no-floppy --set=root 6CFD-C181
    chainloader (${root})/EFI/Boot/bootx64.efi
    }

    6CFD-C181 is the UUID of your efi partition. The other are to the real recovery partition or incorrect one's from grub2's os-prober.

    Re: Can't boot to Windows

    Yeah, I read the link you posted and those 2 should work, but it says image not found or something like that. Any ideas on something else I can try? Also, would reinstalling be a good idea?
    On that note, do I have to uninstall ubuntu before I can reinstall it? If so, how would I uninstall?
    Thanks for all the help oldfred

    If you use Something Else and choose the same / (root) partition as you now have, same /home (but do not reformat) that will reinstall and save any user customization and data you have. But you should not have to.

    There really should not be any difference in booting Windows from UEFI menu or from grub chain loading back to the same efi file to boot Windows. Windows boots ok from UEFI menu.

    Is secure boot on or off? Some only work with secure boot off.

    I think it's on, I'll try it with secure boot off I guess and report back.

    Yeah, turning off secure boot worked. Everything seems to be running fine now. Thank you so much for all the help

    Glad that worked.

    Some systems boot only with secure boot off. Others will boot with it on or off. Since Ubuntu has the Microsoft key, it is the vendors version of UEFI that needs updating, so if they have an update to UEFI/BIOS later on, then it may work.
