Booting has failed!

Hi,

I powered off the system when Mandriva was booting halfway since there were many error messages. When I powered it on again, I was not able to get it to boot again, even with failsafe. Here's the ending messages:

EXT3-fs error (device sda1): ext3_check_descriptors: Block bitmap for group 0 not in group(block 2302390)
EXT3-fs: group descriptors corrupted!
mount: error mounting /dev/root on /sys/root as ext3: Invalid argument

Switching to new root and running init

Booting has failed

How do I fix this?

Thanks!

Oh crap, I ran e2fsck on it and that seemed to make it worse. The file system is now ok, but it still won't bootup...

Can I reinstall Mandriva over the existing partitions and still keep the my files intact?

Re-install will remove all data. Back-up data before doing that.
Does it throw same error now?

It still says booting has failed, but now it's a different set of errors.

I have another Mandriva box(2008.0 instead of 2008.1) that I can probably connect the faulty drive back things up to. How do I mount it though? I tried doing a mount but it gave me an error, I think unknown file system or something like that.

Try using ext3 filesystem.

mkdir /media/sda1
mount -t ext3 /dev/sda1  /media/sda1

/media/sda1 is mount point and /dev/sda1 is device name assigned to partition.

Execute fdisk -l command to check device names assigned to partition(s).
