i nuked my grub, is this guide safe? rm-ing anything I don't understand entirely is scary
@synthgal oh yeah, that should be fine then
@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?
@synthgal hang on, rescue mode? I thought you were just doing a reinstall
Okay that changes things substantially, sorry, should have realised that was what was going on
What's the current situation when you boot?
@troubleMoney grub just doesn't show up.
It's not in my UEFI settings boot order. Goes straight to windows.
@troubleMoney I was trying to get a SparkyLinux dvd to boot and someone suggested temporarily switching to legacy boot to just see if that's the problem and not installing under it.
I did that, and the dvd didn't boot so I changed back and grub was just gone.
@troubleMoney the CentOS installation disk emergency shell is where I'm trying to do this from
@synthgal okay, cool, so you're chrooted in to your centos install? If you're not, then do so
then you'll want to do "/sbin/grub-install /dev/[your hard disk]", your hard disk will be in the form of hda or sda or something similar
After that check that there isn't anything obviously wrong in the /boot/grub/grub.conf file and reboot, that should fix it
@troubleMoney grub2-install: error: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist. Please specify --target or --directory
@synthgal is grub2-efi-modules installed?
@synthgal cool, if you try /sbin/grub-install /dev/[whatev] again it should hopefully find that file
@troubleMoney just to be clear, I want /dev/sda, not /dev/sdaX? isnt GRUB supposed to be in that boot partition with EFI?
@troubleMoney CentOS 7. I just wanted to make sure I wasn't using a guide to do a different thing, my reading comprehension goes down as my stress goes up
