Does the system loudspeaker also ring like a firebell? I just recovered
from the same situation - and your grub.conf confirms it is very likely
the same problem I had.
The latest kernel update 2.6.25.3-18.fc9 - or one of the 199 files
updated at the same time - rewrote grub.conf so that (in my case) the
line which should have read:
kernel /vmlinuz-2.6.25.3-18.fc9.x86_64 ro root=/dev/VolGroup00/LogVol00
rhgb quiet
actually read:
kernel /vmlinuz-2.6.25.3-18.fc9.x86_64 ro
root=UUID=ab562fb5-0a9a-4458-9f30-61c8a23f774a rhgb quiet
Somehow my /dev/VolGroup... had been changed to UUID=...
The same error had been applied to the previous kernel (2.6.25-14.fc9)
so that neither would boot.
In short, boot the computer with F9 DVD, choose "Rescue previous
installation", press OK to go to CLI, type "chroot /mnt/sysimage", and
type "cd boot/grub".
"ls" will list, among others, grub.conf. Then type "vi grub.conf" and
edit the kernel lines to contain *your* /dev/filesystem instead of your
UUID. Then ":write" to save your new grub.conf and ":quit" to exit vi.
Once in CLI, type "exit" *twice* and remove the DVD while the system is
closing down. It will reboot automatically.
