An Ubuntu (Hardy Heron) server here died a couple of days ago. Fortunately, the hard drives were OK. So now we have a new server with the old disks installed.
The new server won't boot. After a number of lines in the boot sequence, it says that it can't find the drive with a particular UUID. I used a (Fedora) rescue disk to modify the grub menu to look for the actual device, /dev/sda1. The failure still occurs with the error message mentioning the device name instead. The hard drive is certainly there, because that's where the system is attempting to boot from, and finds grub.
Do I need to rebuild the /dev directory? How can I do that? Is there some other issue?
