Error while booting ubuntu 23

gp flag

Getting this error inconsistently- Unable to mount root fs on unknown-block(0,0).

Sometimes it boots successfully and sometimes it throws this error.

I tried installing from different USBs , but no luck.

Any idea how to resolve this permanently ?

Ubuntu 23? Ubuntu's main products are *year.month* in format, so do you mean Ubuntu 23.04? or something else? Are you using Ubuntu? If you are using Ubuntu, did you verify the ISO, was it written correctly with updated software? (*some older software can only write ISOs for releases up to 20.04 for example*)

Yes its 23.04, the error is very inconsistent. Sometimes Ubuntu gets booted and I can login and work on it. But if restart or shutdown and again try to login this error pops up. When I logged in, I checked for all software updates. Its correct. I even ran sudo apt-get update and updated it all.

This isn't a forum, your question still doesn't mention a release (*and any answers will be to your actual question, not subsequent comments made by readers about that question - this is a Q&A site remember*). Also be specific, 23.04 has many ISO choices using different installers and you've not yet said what 23 (.04) product you're asking about. I'd have booted to *runlevel 1* and looked for clues in logs, have you? Systemd journals survive reboot, though a failure to boot may leave few clues.

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.
