Ubuntu 20.04 Cannot Boot Due to Missing Modules

kn flag

When trying to boot up my laptop I'm presented with an error message saying:

"ALERT! UUID=199df2c0-c427-4e87-9edf-b64a88ccb54e does not exist. Dropping to a shell!".

Most other answers for a similar problem involve changing boot or UEFI settings, but the problem is that I cannot change them due to the fact there is no password setup for the UEFI settings menu (I assume there is a factory setup password or something).

I've tried booting from a flash drive I have but every time I try I'm presented with a message saying that Secure Boot forbids booting from hd01 (my flashdrive). I would assume that I could turn off secure boot in the UEFI settings, but again, I'm blocked out because there's no actual password for it (at least to my knowledge). Is there any way I could change my boot settings in the grub menu or anywhere that I would NOT need to go into the UEFI firmware settings?

This message is telling you a disk partition with that unique ID (UUID) cannot be found, meaning someone may have deleted a partition, OR you have failing disk. It's usually a result of mistakes made during the last working session (*eg. partition deleted*) OR hardware issues you should explore and they are best explored using uEFI/Settings or *live* media and not booting the system (you want the disk not in used for exploration). *From the live media you could perform file-system checks, if errors are found & corrected you can expect normal boot after that too*

Any chance its 5.15.0-53 kernel ? Try to revert to previous kernel on Advanced Options. I believe there is a bug, see if this matches with you. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1998266

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.
