SOS! Cannot boot Ubuntu, emergency mode, pr.cpu0._pdc error

pl flag

I just powered on my laptop, it said checkdisk is needed, but checkdisk stopped after about 30% and went into first picture's screen. After ctl -xb I faced several errors as in next pictures.

I was running ubuntu 20.04, and tried installing 21.20 but I face the same error. looks like a firmware or efi problem.

As you running Ubuntu 20.04 or 21.04? Have there been any firmware updates applied lately?

I am running 21.04, and some firmware updates might have been there recently. Looks like EFI problems? I am completely unfamiliar with these kinds of things

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.
