which they really aren’t in the first place I’ve used it and never had a problem

to my knowledge the anti cheat is basically disabled anymore

is it possible he forgot to select pro in the install menu a pro license will activate home no problem

should work just fine just look at the wiki for os-prober to get it in your grub menu

if your using grub you just need to install os-prober and re build your grub config and then you can boot windows from grub even on multiple drives
