Dual-Boot Disaster? OHNOES+WOES!!

[istigkeit]

I am trying to set up a dual Windows-Ubuntu boot, but seem to have run into a bit of a problem. I've done a little searching and research, but can't seem to find what I need to take care of this, so hopefully someone can provide me some help or point me in the right direction. Thanks to everyone in advance.

I have a regular C: drive with my normal XP install.

I also have G: drive which is an external USB hard drive. This has no operating system, just backup files. I chose to install Ubuntu here.

I did the regular side-by-side install from my live cd and it seemed to go smoothly. I was prompted that the install was successful and I re-booted.

While booting, I only get a "File not Found" message and a "rescue grub" prompt.

From here, I don't know what to do.

This is what I get if I do sudo fdisk -l

From what I can tell it is installed and all my files are intact.

What have I done wrong?

Grub in Karmic is rather new so let's learn together. Can you navigate to your Ubuntu partition and post the contents of the following file:

/boot/grub/grub.cfg

Don't modify it, cause we don't want more mess then there is already.

did you have an older version of Ubuntu installed before?

It appears that file contains nothing but a plain text file named grubenv
