Kernel Panic:vfs: Unable to mount root fs on 307

Hi,

I think this message just means it doesn't know which is the root partition. Assuming you know what partition it's on you would just pass parameters to lilo at boot time. So, you get the 'boot: ' prompt (exit any graphical screen first with control-x) and type something like :

boot: linux root=/dev/hda7

(where /dev/hda7 would be your correct root partition).

The 03:07 refers to the major and minor device numbers. Block major 3 is the first ide drive (/dev/hda) and minor 7 should be partition 7.

If it works you need to edit /etc/lilo.conf and put 'root=/dev/hda7' on a line in the linux 'image' block so it looks something like this :

image=/boot/vmlinuz-2.4.12
label=linux
root=/dev/hda7
read-only

Then update the binary lilo with '/sbin/lilo -v' as root.

If this doesn't work try tom's root /boot disk to boot linux and be able to run fsck on your partitions -->

Good Luck !!

Hi,



Update to the above.. actually, thinking about it a bit more - have you changed your partitions recently ? If so, the device numbers of the partitions may have changed and that could be why you can't boot - lilo is trying to access /dev/hda7 when it should be /dev/hda8 or whatever.
