I tried upgrading from 20.04 to 22.04.1 as the os suggested, after reboot I get

Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I tried following this: Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

but it did not help, also it removed windows from my boot menu. (I am on dual boot, can still boot windows but only if i press F12 to get advanced boot menu and so on)

I am using a live usb (try ubuntu) because I cannot boot any kernel from the advanced boot menu. I tried from that link the thing with mounting the file system and running commands there, the commands seemed to work but ubuntu will still not boot.

I also tried following this: Failed to reboot after upgrade from 20.04 to 22.04

but it didnt work either.

ls in the /boot directory shows this:

config-5.8.0-45-generic       initrd.img-5.8.0-45-generic
efi                           initrd.img.old
grub                          memtest86+.bin
grub.bak                      memtest86+.elf
initrd.img                    memtest86+_multiboot.bin
initrd.img-5.15.0-25-generic  System.map-5.8.0-45-generic
initrd.img-5.15.0-43.46       vmlinuz
initrd.img-5.15.0-43-generic  vmlinuz-5.8.0-45-generic
initrd.img-5.4.0-56-generic   vmlinuz.old

and ls -al /boot shows

total 95148

but im guessing some of the things i've tried might have affected the output, im unsure.

Any help will be greatly appreciated

  • did you run the exact command from the other link? you should replace the kernel version with your own: 5.8.0-45-generic – Cagri Sep 14 '22 at 18:01
  • oh also, on a live usb, you need to mount your filesystem and chroot, https://www.turnkeylinux.org/docs/chroot-to-repair-system – Cagri Sep 14 '22 at 18:03
  • I did that the first time with the version you wrote, it seemed to work but I still cannot boot, same error. I tried the other versions because i saw them in ls, but even though the first version "works" i still cannot boot – Elam Buteil Sep 14 '22 at 18:04
