    Lost Windows dual boot after Ubuntu 24.04 upgrade

    Here are the results of boot-repair that I ran just a bit ago. I appreciate any help you can give me on this. I'm not that well versed on the root level of Linux & how things can get mucked up from just upgrading. I don't want to get to far out on my own here without somebody guiding me on how to proceed. Thank You.

    Suggested repair: ______________________________________________________________
    
    
    The default repair of the Boot-Repair utility would reinstall the grub2 of
    sda6 into the MBR of sda.
    Grub-efi would not be selected by default because no ESP detected.
    Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix
