I want to use a new motherboard with an old disk. The disk has just one partition, with Debian/jessie installed. On booting, Debian is found and begins to start up with usual dmesg output lines. After the line
Begin: Waiting for root system ...
the system hangs a while, then writes
Gave up waiting for root device. ... ALTERT! /dev/idsk/by-uuid/... does not exist. Dropping to a shell! ... /bin/sh: can't access tty; job control turned off (initramfs)
Next attempt: I booted from a Debian netinstall CD into rescue mode. When executing a shell, the disk was found. I then reinstalled Grub to the disk. However, on rebooting from the disk, the above behavior hasn't changed.
