I think I screwed up my computer (Ubuntu/GRUB problem)

Rikash

So today I decided to install Ubuntu, and all was going well until I decided to restart to go back to Vista side. As soon as I did, however, my computer comes up with the message
"GRUB Loading stage1.5.

GRUB loading, please wait...
Error 22" and stays there.

I've attempted to use the recovery disks that came with the computer, and the first one seems to work, then it asks for the disk with the drivers; then it does... something for a while, and doesn't ask for the 2nd recovery disk, just restarts and brings me back to the error message.

Thanks for any help you can give me.

Sounds like GRUB overwrote your master boot record, so your computer can't find Vista any more.

You need to get into a windows rescue mode type thing. You can do this with a windows bootdisk, (floppy or cd) you just need to go into the bios and change the boot order to be the floppy/cd first (even take away the hdd as a boot option so it is forced to try hard on the floppy/cd)

then, when you are into windows and get to a commandline, type fixmbr. that should be it.

Supposedly this is a missing partition error.

Let's start with: do you have a Ubuntu boot disk? (I assume so)

Start from it, get to the command line and type in "fdisk -l", please post the output.

EDIT: It seems matthas found the same solution I did....I decided to go for a more conservative approach.

Well, I don't have a windows boot disk, just the recovery disks that came with the computer (which aren't the same, right? Pretty clueless when it comes to computers), and have no idea where I'd find one.

When I typed "fdisk -l", nothing happened, it just gave me the next command line. Thanks for the help so far, anything else you could give me would be greatly appreciated.

Ok, so I can only boot Ubuntu from the disk, and nothing else is working. I'm thinking of just formatting and installing XP (I have the disks) since nothing I have seen has worked. I'm just wondering how I could go about formatting, or if there's anything else I could try.

Edit: Ok, so I didn't realize that you needed to put "sudo" in front of "fdisk -l", but when I did that I got
