Windows/Linux booting problem
 

Hi Linux Folk,
I am not only a linux beginner, but also out of my competence field (I am in molecular biology) and have a problem I could not solve myself. A dear friend installed Ubuntu on my desktop so that I can start entering linux world, and left me a small partition to install Windows XP to run software that have not a linux counterpart. After installing Windows I could not boot Ubuntu anymore. I know it is a common problem and that I should follow instructions on the super GRUB disk webpage. I already did everything they suggest and nothing worked... and my friend is not here now to help me.
I forced booting from Ubuntu using the command line. I followed the specifics in the super GRUB disk webpage and my problem is to load the kernel. It seems it is not in a folder, but directly in the root and I do not know how to specify the path to the kernel. What do I write after: grub> kernel /vmlinuz root=
Any help would be appreciated. Please, remember I have not computer skills and do not know anything about Linux, yet.
Thank you
Elisa

Ubuntu is a Live CD.
So, boot up the Live CD and when it is up and ready, open a terminal via Application or similar. Then type this command: sudo fdisk -l. The output of that command should give information on all hard drives seen from the Live CD with all partitions within.
You should be able to copy and paste the output of what that command produces here so we can recommend what additional commands to issue in order to set up the grub boot loader in the MBR of the appropriate disk so you can get a menu containing all operating systems installed where you would just highlight the one you want to boot and hit enter to boot it.
