That sounds like grub is > messed up now and can't find it's modules. BIOS GRUB has two kinds of prompts: grub> grub rescue> If it is the former, that means it did find modules (well, in particular it found normal.mod at least), but did not find grub.cfg. That's curious given the sequence we know so far. If it is the latter, then we're in core.img (stage 2) only, and it didn't find either grub.cfg or modules. This means core.img isn't pointing to the proper grub device and path, which is ordinarily baked into the core.img by grub2-mkimage which is part of what grub2-install does. So... yeah it's kinda confusing. But ordinarily a grub2-install /dev/sda will fix that. But I'm not sure in what environment the commands are being issued. grub2-install can be pointed at an alternate root, but grub2-mkconfig is kinda fussy, and doesn't really do the alternate root routine very well. I've only found it reliable to run in a chroot of a properly assembled system. Netinstall rescue option does this for us, but Live boots don't have that so you have to assemble manually: mount /dev/root /mnt/sysimage mount /dev/boot /mnt/sysimage/boot # in this case it's skipped because /boot is a dir on sysroot mount -B /dev /mnt/sysimage/dev mount -B /sys /mnt/sysimage/sys mount -B /proc /mnt/sysimage/proc mount -B /run /mnt/sysimage/run chroot then do grub2-mkconfig -o /boot/grub2/grub.cfg then reboot I don't know if all of those are needed. /run probably isn't.

Also backup your /home files just in case. I agree. This is probably more grief than it's worth. Backup /home to some other drive entirely. And obliterate /dev/sda with automatic partitioning, using "reclaim space" to also Delete All. Or if allergic to both LVM and Btrfs, use "Custom-Automatic" UI, i.e. choose Custom, pick the Standard partition scheme popup, then the blue text to create partitions automatically. Install. Two independent backups for anything important. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
