Hi,

Today I have been unable to boot into my Ubuntu (10.10) or Windows (7) partition.

Ubuntu kernel panics on boot with the error:

init: hash.c:296: Assertion failed in nih_hash_search: hash != NULL

I can boot into a LiveUSB environment, and from there can access all my files on my 3 partitions (1 ext4, 2 NTFS). I have also ran fsck on the ext4 partition and ntfsfix on the 2 NTFS partitions, both not finding any errors at all. And Grub is intact and have also tried a reinstall of it.

So at the moment I'm currently stuck using a LiveUSB, and would like to see if there are any other options other than reinstalling.

Thanks.

Update

I've now ran chkdsk using my Windows recovery disk, and it found errors and fixed them, but I am still unable to boot into either Windows or Ubuntu

Update #2

I've decided to just re-install Ubuntu and start again as I didn't really want to spend any more time looking around whilst I need this computer for work. Thanks for all your help though.
