Grub Error 22

[dagarshali]

Hi,
I was using gparted to make a partition and i hit create particle by accident and when i rebooted, I am getting a grub error 22. I have installed 9.10. Can anybody please help me fix this problem.

Boot from a live CD, open a terminal and post the output of
sudo fdisk -l
sudo grub
find /boot/grub/menu.lst
quit
The -l has a small L rather than a one, and you need to post the output of the find command before you type quit

Are you sure there wasn't more to the sudo fdisk -l ? There should be partition data under it.

hi,
yes i am sure that is all i had... ..Is it because is used the create partition table..which by the way started this whole thing..

It looks like there is no partition table. Yes, "create partition table" actually means "destroy the existing table and start with a blank slate. All information on the drive will be inaccessable." Before continuing, I need to know if there is information on that drive you want recovered. If so, there needs to be a focus on that before trying to reinstall karmic, or it'll all be lost.

[dagarshali]

yes D-cat,
I have important data that i would like to restore...i am running a program called testdisk after i got a partedmagic live cd.. i think it is listing all the drives there..i am not sure how to restore those though?

I'm not exactly syre how testdisk works, but I'd take note of the output a/o keep the log safe (if you went that option). When testdisk finishes, run sync, then do the sudo fdisk -l again. If the partitions are listed, then you're in good shape (I'd still do a fsck on each one to fix any possible errors resulting from the partition table loss).

If it still lists no partitions, show me the output a/o log from testdisk.

Click in Testdisk option in Partedmagic Menu, select Create -- Proceed -- 'Intel' -- Analyse...

TestDisk will restore lost partitions and rewrite partition table.

Hi,
this is the output of the testdisk-->analyze and then followed by deeper search..this is the output..i have made some comments on what i noticed when i try to list files in the list..

I could list files for all other partitions except Linux Swap..

Now the problem is how to choose the type of partitions for these things..

The main partition for linux is the 66GB one.. I have windows vista installed as well.. and boot to ubuntu using Grub..
