View Full Version : [ubuntu] GRUB error 22

March 16th, 2009, 10:46 PM
Hi everyone,

This is my first experience with Linux so excuse my limited knowledge. I burned the boot cd, booted up and installed ubuntu what i thought was successfully. However, when i was struggling to get my wireless connection set up, I decided to go back onto windows vista to do some googling.

So i restarted and got the option of a few different things, i chose windows vista/longhorn and it loaded for a bit before a big error message came up. I can't remember exactly what it was, but it mentioned recovery.dat and I couldn't do anything so i had to force a shut down.

I turned the computer back on and this is when I got the GRUB error 22. It occurs when doing something regarding stage1.5.

I am currently running off the ubuntu live cd. I tried working through https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows#Quick%20Sta rt but was unsuccesful, I kept getting the file not found error.

After my research, I believe the following information may be of use. It is the result of fdisk -lu

I would be very grateful for any help concerning this matter, as I currently can't access either of my operating systems!

Come to think of it, your partition table does look rather ... eccentric. For contrast, my Vista/Ubuntu dual-boot machine's partitions look like this:

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors

Disk identifier: 0x2a182a17

Device Boot Start End Blocks Id System

/dev/sda3 56163240 156296384 50066572+ 83 Linux

How, exactly, did you go about installing Ubuntu?
