Grub Boot error

[obnascar]

I just did fresh installs of Freespire on hdb1, Mandriva on hdb2, Kubuntu on hdb3, hdb4 is swap and I use hda1 for storage.

After these clean installs, I changed my mind on the size of the partitions, I used Qparted to resize, I know one takes a risk when resizing, so that was no big surprise. Now, when I boot up Mandriva, it gives me the follwing error:

Kernel panic-not syncing: VFS: unable to mount root FS on unknown -block (3.66)

What would be the correct thing to do to get Mandriva to boot back up again ? If anyone needs to have me post my Kubuntu /boot/grub/menu.lst, please let me know.

Re: Grub Boot error

Did you check whether you have a filesystem?

Maybe run fschk to check the filesystem.

I don't know if a destroyed journal could generate this message? Otherwise you might repair the journal with
tune2fs -j /dev/hdbX

How does one go about that ?

Re: Grub Boot error

sorry, see I mixed up fsck with spoken language

in a terminal, run fsck -c /dev/hdbX

for more info: man fsck (or fsck --help)

in a terminal, run fsck -c /dev/hdbX

This is as far as I went, do I want to answer YES ?

obnascar@MadTux:~$ fsck -c /dev/hdb2
fsck 1.38 (30-Jun-2005)
e2fsck 1.38 (30-Jun-2005)
/dev/hdb2 is mounted.

WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Do you really want to continue (y/n)?

is that warning usually there ? It scares me......lol

Re: Grub Boot error

maybe unmount it then

umount /dev/hdb2

then try again, don't know if it will resolve your problem in the end, but it is the only thing I can think of (says more about me than about your options )

Re: Grub Boot error

I actually figured out to umount it after I posted. Looks like it will take a while.........................

I even did a reinstall of Mandriva a while ago, but it still will not boot. I think there is something in the file system that Mandriva does not like. After this fschk I think I will try installing OpenSuse 10.2 on the same partition and see what happens......

Re: Grub Boot error

ok, maybe then post relevant piece of menu.lst and /etc/fstab, maybe someone knows?

PS: can you access files on hdb2?
