I am running Ubuntu 12.04 on a netbook - Acer AS 1410.

After a download session, I restarted the computer and it said:

error: hd0 out of disk. Press any key to continue...

I pressed everything, but it's just frozen there.

Any idea what's wrong with it and what I can do to fix it? I haven't been able to run my computer at all since it's frozen like that. Help please!

I booted the live cd and ran sudo fdisk -lu into terminal, and here's what it gave me: Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders, total 117231408 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x9a696263

Partition table entries are not in disk order

I am somewhat of a beginner in this, so don't know what this means. any ideas? Thanks!
