kernel panic - not syncing : VFS: unable to mount root FS on unknown-block


Hi all,

I have an old machine (Dell PC running FC 2) that died on me. CPU & HD failure, however I do have a backup of the HD. I placed the backup HD in another machine (Boxx PC). Yes 2 totally different hw types. The disk is a scsi disk, the new machine sees the disk, but when it boots I get the following error: "kernel panic - not syncing : VFS: unable to mount root FS on unknown-block".

Here is what is in my grub.conf:

#boot=/dev/sdb1
default=1
timeout=10
splashimage=(hd1,0)/grub/splash.xpm.gz
title Fedora Core (2.6.10-1.771_FC2)
root (hd1,0)
kernel /vmlinz-2.6.10-1.771_FC2 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.10-1.771_FC2.img
title Fedora Core (2.6.10-1.771_FC2smp)
root (hd1,0)
kernel /vmlinuz-2.6.10-1.771_FC2smp ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.10-1.771_FC2smp.img
title Other
rootnoverify (hd0,0)
chainloader +1

I'm thinking once I boot the system in single user mode I can run a make to update the drivers with the new machine.

Any ideas or recommendations would be welcome.

Thanks,

How many hard drives are in the new machine? It would help if you could provide more info. Maybe the output of
fdisk -l (from a linux liveCD if you are unable to boot into any linux partitions on your new machine.)

not likely
those hdd drivers are in the kernel and there is NO WAY to use the current fedora 14 kernel in fedora 2
fedora 2 is way way too old to even run on new hardware
it was released on May 18, 2004
the end of life for fedora 2 was back in 2005

mount but do not boot to the old one and back up your data
and install a current OS

This is the only HD on the new machine.

in all likelihood you will never get fedora 2 on a old hdd to boot in a NEW computer
fedora 2 is just way too old to work on new hardware
the main issue would be the hd?? VS. sd?? problem
fedora 2 put the old ide on hd?? and the newer sata on sd?? partition labels
the current os's fedora,suse,rhel, all use sd?? for everything

use the existing and WORKIGN operating system on the new machine to mount the old fedora 2 disk
back up it data
and install a current and supported operating system
the current fedora is Fedora 14

now that fedora 2 hdd will work in a identical machine it was in from ? 2002 ? or so

there have just been WAY too many hardware chances from the old computer to a new one for a dead version of fedora to ever boot
