    Great “how to” site!
    A bit hard to locate Grub2win videos, since most are Linux on VMS and got lost looking for Mint on W11 vids! And Youtube is such a super drag because of it ads, and then they have ads, after ads, and if we don’t sell out souls, “info,” than we get stuck in an ad loop, without getting out!
    So, do you have a sight that hosts you vids with a good search for Grub2win on Windoes 11 with Mint?
