Failed update - grub now broken

[HughF]

Hi, I ran upd today and let it do an update but I was distracted and timed out at the password prompt when everything was installed.

I rebooted later that day after shutting down my machine and I’ve now got grub issues. I see the welcome to grub message in the top-left but then my system drops into the bios. I don’t see a grub menu. Perhaps the EFI bios is set as the default entry?

I’ve done the following, using a live-usb (although one that doesn’t include time shift utilities, or I would have just restored the pre-update snapshot):

1. Mounted and chroot’d into the partition, checked /boot/grub-btrfs.cfg and that all looks fine.

2. Mounted and chroot’d into the partition, checked the output of efibootmgr -v and that shows the default is set to the device with grub installed, and the file is \EFI\GARUDA\GRUBX64.EFI

3. From the live-usb, run Garuda Boot Repair and repaired the grub configuration file. This found all the entries I was expecting but didn’t restore normal operation. I tried this first.

Just wondering what my next steps are?

Fixed it:

Re-ran garuda boot repair and re-installed Grub into ESP. Then re-ran the grub config repair option.

I don’t get a graphical grub, instead getting a bunch of ‘out or memory’ errors, but at least it boots.

GRUB downgrade

A few days ago a bug was reported on the latest version of grub that affected many (but not all) users.

Since the fix was not effective for some users, and other problems were reported (not necessarily linked to that fix), it was decided to downgrade the Gurb package, in the Garuda repo, to the latest working version. See below the main thre…
