[SOLVED] Unable to boot middle of upgrade F35

przemhb · 08-02-2022, 04:20 PM

I run Fedora 35 installed on a microSD card in Dell laptop, which has W10 as default system on SSD M.2 drive. I use Fedora from time to time.

Ending June I have tried to perform upgrade (or was it just an update?), but something failed as when the upgrade process rebooted it started Windows. From the time when I choose to boot from the microSD card no Grub2 screen is shown and laptop just reboots and starts Windows.
I have took the card and checked it on another Fedora machine. There are no errors on the card. Boot partition has properly set boot flag.
Furthermore there are still files like in the var/lib/PackageKit/:
- prepared-update (linked from the /system-update)
- transactions.db
- offline-update-action

I'm wondering what might have gone wrong and how to fix it?

With the MicroSD attached, boot any Linux distro in UEFI mode, run and post here input/output from:

Code:

lsblk -f
efibootmgr

You should already be able to strike the F12 key during POST to bring up the BBS menu. There should be a selection there labeled Fedora in some manner, which should be enough to boot into Fedora. Whether it works or not, on next Linux boot in UEFI mode you should be able to run the following logged in as root:

Code:

efiboogmgr -o 3,C,0

and on next boot attempt have your Grub menu back. Report back with results.

You're right - Fedora was missing from the boot order. It appeared when I added it back as you've wrote. Thank you!
