I had some problems updating my old 20.04 to 22.04.After my initial update my kernel was still at 5.4.0-174.
My system was starting but not everything was working.I've upgraded my kernel using the command apt-get install linux-image-generic-hwe-22.04
After the upgrade it looks like the system is starting. But after a while the screen gets blank with a cursor. You cannot do anything anymore.
Opened another terminal using shift, alt , F2 and did a reboot to safemode. From safemode I can get to normal boot.
I've tried sudo apt install --reinstall ubuntu-desktop but that did not solve the problem.
In the messages passing by I saw Grub failed boot detection.
Any help?
