I was having problems performing an update yesterday that failed on dovecot dependancies and after a few tries I removed dovecote (it wasn't being used) from the installation and tried again. Everything seemed to be going OK then the update (about 160MB) hung and the screen went black a few times and I think then shutdown automatically.
The PC then fails to reboot and displayes the message
"Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)"
I have tried to get the PC to boot with the super grub disc but without success (probably my in experience)
I have also tried a suggestion from one of the forums to start the PC with a live CD and typed su -c 'grub-install /dev/sda at the terminal again without sucess.
I have looked at the files with the live CD there are grub, menu and kernel files there (some are in lost + found, b ut don't know wheer these should be so have not changed anything.
Is there an easy way for the in-experienced to repair the boot process ?
The PC is a pentium 4 running Fedora 13
There is a 200MB boot partition formated as Ext3
and a 19GB partition formated as a LVM with Ext4
There is a CD drive but no DVD
Everything has worked OK for the past year through two online upgrades.
Many thanks in anticipation
