This problem seems centered around me, it has happened twice!
Description of the Problem
My Linux partition (ext4) got corrupted. I believe a bad superblock ...
So when I boot my computer I get no grub just a flashing monitor.
I fixed it using Windows 7 DVD.
Last Time this happened
I accidentally formatted my Ubuntu partition and so I reinstalled Ubuntu (10.04 32 - bit).
When this problem pops out
When grub updates I believe .. because the last time I got this error was when I updated grub.
This time also I was updating Ubuntu from 10.04 to 11.04 and grub got updated and the partition got corrupted!
Any idea how to get my Ubuntu partition back and what is causing this problem?
Clarifications
My entire ubuntu partition is corrupted !!!
