umount/initrd/proc failed :2 kernel panic: no int found


Hi there!

I have both windows XP and fedora core linux on my laptop. Yesterday I was in linux and just gave one file search ( that was taking long) and I stoped it in between and then I inserted one pendrive (which earlier also I had used with this laptop) and I found that there is some problem in saving the file in vi editor, it became just read only mode. Then I rebooted the machine but got following messages:

Ext3 -fs : šan't read group descriptor 1
mount :error 22 mounting ext3
pivotroot: pivot_root (sysroot,/sysroot/initd) failed :2
umount/initrd/proc failed :2
kernel panic: No init found
try passing init =option to kernel

then it hangs


I tried to see answers of similar questions but, could not do any thing. I tried some kernel options from ""grub>" but could not succeeded.

I do not have botable CD for this linux. I had installed many related software on this linux so I do not want to loose it.

Is there a way to fix this problem? I have one bootable Knoppix linux but that too not taking me to my that partion of the system, means I could boot it through Knoppix bootable CD but couldnot access my earlier files.

If possible please help me.

Thanks,
Mini

Very strange indeed, let's make sure and check some settings first things first: boot up your Knoppix CD. Do you have a sepparate /boot partition? Try using the Knoppix cd to mount the root ( / ) partition of your installed linux system, and if you have a /boot partition, try mounting that too. If you don't know what devices to mount, "fdisk" might be of assistaince in pointing out your linux devices, give a paste of "fdisk -l" here if you still can't figure it out. If you don't know how to mount partitions, "man mount" should give you a clue.

Let's say you don't have a sepparate /boot partition, then give us the output of:

Code:
cat /mount/point/of/your/installed/root/partition/boot/grub/menu.lst
If you *do* have a sep. /boot partition, then give us the output of:

Code:
cat /mount/point/of/your/installed/boot/partition/grub/menu.lst
and the output of:

Code:
cat /mount/point/of/your/root/partition/etc/fstab
For example: if I mount my "boot" part to /mnt/my_boot and "/" to /mnt/my_root, I'd have to:

Code:
cat /mnt/my_boot/grub/menu.lst
cat /mnt/my_root/etc/fstab
Only "/" (no sep. "/boot"):

Code:
cat /mnt/my_root/boot/grub/menu.lst
cat /mnt/my_root/etc/fstab

Here I am getting more than 1 page on screen, so not copying here.

Please tell me whether this much information could be of any use?

I could not find boot partion of my linux system.

Thanks,
Mini
