I'm sorry for the game of 20 questions... I'm just trying to get as
clear a picture as I can so as to avoid doing anything that can
potentially be harmful.

Now, I'll assume that the notebook has one hard drive, detected as
/dev/sda However, it's important you verify this.  type the mount
command, and note what drive/partition / is mounted from.  I'm guessing
/dev/sda2.  If, however, it's /dev/sdb2, then use /dev/sdb in the
following grub shell commands instead of /dev/sda


The first partition is the Windows NTFS

The second partition is the Linux /

And there's probably a third partition for Linux swap

Enter the grub shell with sudo grub

In the grub shell, give it these commands:

device (hd0) /dev/sda

root (hd0,1)

setup (hd0)

quit

You might also want to check the grub menu.lst and make sure the root of
the Ubuntu Boot as well as the Widnows boot secions are (hd0,1) and
(hd0,0), respectively  (although, that can be changed from the grub boot
menu once that is working properly)
