Can no longer boot from the default kernel

Recently I found I couldn't restart google-chrome after I had tried to shut it down so I rebooted. The computer didn't shut down properly so I powered off and back on again. When the computer tried to come back I got to the grub prompt and pressed Enter as I always do but then the screen went blank and the system never came up. I tried another few times and the same thing happened.

There are two options for the kernel in my grub

5.15.0-53-generic
5.15.0-52-generic

with the first one being the default.

Out of desperation I tried the second one and this works!

What can I do to fix the 5.15.0-53-generic option? I don't know what broke it.

Check of all packages are correct installed. If you have any closed source modules on your system like nvidia or other check with `dkms status` Make sure you have enough place ond inodes free if you have an own /boot filesystem.

@nobody I don't have nvidia but how do I do the check you mentioned?

nvidia was only an example. Please [edit] your question `dpkg -l | egrep -v '^ii|rc'` and `df -h;df -i` and `dkms status` if your system says dkms not found forget the last one. It could also be some kind of problem with the kernel itself.

I would remove the not running kernel and wait for the next one.

@nobody The kernel ran for a long time happily so I must have corrupted something.

Then try to reinstall the packages,

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
