i nuked my grub, is this guide safe? rm-ing anything I don't understand entirely is scary

@synthgal looks fine to me assuming you're using redhat or equivalent

@troubleMoney should I -r that first rm command?

@synthgal do it as written

@troubleMoney it's giving me "cannot remove, (x) is a directory" errors

@synthgal hm, you can probably ignore those, grub only looks for files with a number in front of them IIRC

Probably best to keep to the guide, the one who wrote that knows more than I do about it

@troubleMoney christ, I think this guide assumes I have a network connection because I have to yum stuff :D

@synthgal oh yeah, that would indeed be an assumption, yeah

@troubleMoney thank you based Sam

had to do a little DNS stuff but nmtui was a lifesaver

@synthgal oh god yeah, nmtui is super useful and good

@troubleMoney okay hopefully last question

since I'm using centos and not redhat, would I change /boot/efi/EFI/redhat/grub.cfg to /boot/efi/EFI/centos/grub.cfg?

Other grub guides explicity for centos do it this way but it's a deviation from the repair guide

@synthgal yeah, point it at the one with centos in it

@troubleMoney well that seemed to do nothing at all.

the rescue mode had me chroot to mount my partition, that woun't change anything?
