VFS cannot open root device LABEL 00:00
 

I have a dual booting of "fedora core and Windows XP" in my PC.

Now the fedora is not booting properly. It's giving the following error.

RAMDISK: Compressed image found at block 0
Freeing initrd memory: 162k freed
VFS: Mounted root (ext2 filesystem).
Red Hat nash version 3.5.14 starting
Loading jbd.o module
Journalled Block Device driver loaded
Loading ext3.o module
Mounting /proc filesystem
Creating block devices
VFS: Cannot open root device "LABEL=/" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00


I had seen there so many post in the same issue.. But i could not solve the issue.

This is the kernal boot options in my pc.

root (hd0,2)
kernel /boot/vmlinuz-2.4.22-1.2115.nptlsmp ro root=LABEL=/ rhgb
initrd /boot/initrd-2.4.22-1.2115.nptlsmp.img

I had changed the root device LABEL into
"root=/dev/hda2" [and other numbers]

then the error came like this..

RAMDISK: Compressed image found at block 0
Freeing initrd memory: 162k freed
VFS: Mounted root (ext2 filesystem).
Red Hat nash version 3.5.14 starting

VFS: Cannot open root device "hda2" or 03:04
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 03:04

I want to take the data backup from fedora.
please help me to solve this problem.

Thanks,
