GNU/Linux + Manjaro question :
I changed all my PC parts except SSD/HDD, but when I boot, Grub says it does not find partition with UUID xxxx...
Do I need to regenerate UUID + modify fstab via LiveUSB ?
Do I need to reinstall udev mkinitcpio kernel to trigger hooks and rebuild configuration ?
Or maybe I'm totally missing the real problem...
@Matthieu grub-install is the command you want on most distros. Make sure your /dev is mounted in the chroot too. When grub fails to boot, the grub-shell does have tab completion, so you can run `setup(hd<tab>` and see what it can detect and figure out what's going wrong that way.
@djsumdog also idk why, keyboard does not work in rescue shell 🙃
