The system seems to try to mount the root file system, which seems to be specified in the fstab by UUID. It doesn't. This can have several reasons: 1) the root fs is somehow broken 2) some rescue procedure has changed the UUID 3) perhaps some more > Am I supposed to be able to sort it out from there? In theory, yes. Knowledge and practice with initramfs doesn't to seem widespread, alas. See here [1]. *If* you know which one is your root partition, you might try to mount it and exit the initramfs shell for the boot process to continue. Alternatively, you might want to boot a rescue system, find out whether you are 1) or 2) above. In case 1) fix, in case 2 boot again with "root=..." and fix your initramfs afterwards. In case 3) try to gather more info and come back :) HTH [1] https://wiki.debian.org/initramfs -- t
