kernel panic after fresh install

| Guys I am having a problem after a fresh installed of Xubuntu 10.10 on my old
| server. I get a kernel panic, the 1st line of the message says:
| 
| Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I think this means that the kernel does not know where the root
filesystem is.

| =========================== sda1/boot/grub/grub.cfg:
| ===========================

| ### BEGIN /etc/grub.d/10_linux ###
| menuentry 'Ubuntu, with Linux 2.6.35-22-generic' --class ubuntu --class
| gnu-linux --class gnu --class os {
| 	recordfail
| 	insmod part_msdos
| 	insmod ext2
| 	set root='(hd0,msdos1)'
| 	search --no-floppy --fs-uuid --set
| 	54f645ad-c340-4618-9657-39ceade647a7
| 	linux	/boot/vmlinuz-2.6.35-22-generic 
| root=UUID=54f645ad-c340-4618-9657-39ceade647a7 ro   quiet splash
| 	initrd	/boot/initrd.img-2.6.35-22-generic
| }

I assume that various lines are broken by your MUA and are fine on
your disk.  Do check.

I wonder if this would work:
 	linux	/boot/vmlinuz-2.6.35-22-generic root=/dev/sda1 ro
(I replaced UUID with a device name.  I got rid of "quiet" and
"splash" because that should put more about the boot process on the
screen.)

Also: you can experiment by typing commands to grub during booting.
Well, maybe.  The 10.10 grub won't listen to me on the one system I've
tried it on.
