Kernel panic - Unable to mount root fs on uknown-block(0,0). Same error when selecting older kernel or trying a liveUSB

My Ubuntu 20.04 LTS Server wasn't responding so I've hooked it up to a mouse/keyboard/monitor. I am running it on an Intel NUC (NUC7i3DNHE).

It's showing the above kernel panic message. I have had this before when an update has failed to install, and remember following instructions to fix it by booting an older kernel version. I'm not sure if it was an auto-update that triggered the error this time but it seems to have been offline since yesterday.

One difference to the other posts I found is that I see multiple messages like check: Corrupted low memory at 00000004ac315r1ea29ab (fee0 phys) = 000 and Memory corruption detected in low memory, just before the kernel panic messages.

Unfortunately I am getting the same unable to mount root fs on unknown-block(0,0) error with any of the 4 boot options I have (2 kernel versions, 2 recovery versions) and also if I try to boot from a Live USB with Ubuntu on it. Do I need to try a different distro?

This means I've got no access to a terminal so I have no idea how to get around the problem. I can't even re-install because it won't let me get to a point where I can boot any OS. What do I do now?

It seems you have a defective or corrupt drive and/or RAM issues.

It was working fine until Ubuntu did an auto-update. I've since tried to reinstall but the only things I can get to actually boot are debian/unix based liveUSBs. I've been able to successfully install Debian but it's giving me the same errors when booting. I've even tried a windows 10 USB (which I have used recently on another machine - works great) but that just shows a blue screen and shuts the PC down. I will order a new SSD for the NUC and try that I guess.

I sit in a Tesla and translated this thread with Ai:

TH: Kernel panic - ไม่สามารถเมานต์ fs บน uknown-block(0,0) ข้อผิดพลาดเดียวกันเมื่อเลือกเคอร์เนลที่เก่ากว่าหรือลองใช้ liveUSB

RO: Kernel Panic - Nu se poate monta root fs pe uknown-block(0,0). Aceeași eroare la selectarea unui nucleu mai vechi sau la încercarea unui liveUSB

RU: Паника ядра - невозможно смонтировать корневую файловую систему в неизвестном блоке (0,0). Та же ошибка при выборе более старого ядра или попытке liveUSB

VI: Kernel hoảng loạn - Không thể gắn root fs trên uknown-block(0,0). Lỗi tương tự khi chọn kernel cũ hơn hoặc thử liveUSB

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.
