From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Help with grub repair/reinstall (lemmy.world)

Hi, out of no where when I boot into my tumbleweed installation (secure boot, uefi), it goes straight to grub rescue, no error messages.

I've tried to follow this guide here: https://doc.opensuse.org/documentation/leap/archive/15.1/startup/html/book.opensuse.startup/cha-trouble.html#sec-trouble-data-recover-rescue-access

However, first of all when I boot into a live cd in rescue mode and login as root, it doesn't find the command "rootvgimport".

Fair enough, continuing the guide and running lsblk shows my lvm installation, but I'm not able to mount it.

When I run "mount /dev/sdc /mnt" it says it cannot mount because it's busy or already mounted (it's not mounted by me anyway).

If I try "mount /dev/sdc2 /mnt" it says unknown filesystem LVM_Member.

Running "mount /dev/sdc2/system-root /mnt" doesn't work either.

Any ideas?

idk, your disk might be corrupted

did you do anything bootloader or disk related before this?

[–] feef@lemmy.world 1 points 1 year ago

No.

Actually I was able to change root into the installation now, but when I run grub2-install, I get EFI var errors, I kinda feel like giving up at this point haha.
