I can't find the exact page that I found the information on regarding 
using Window's boot loader to then load GRUB (here are similar 
instructions to those I found at the time: 
http://www.linux.com/feature/42788 ) , but I found this on the Fedora 
Project's web site:

http://docs.fedoraproject.org/install-guide/f7/en_US/sn-bootloader-advanced.html 


In particular, note the "GRUB as a Secondary Boot Loader" section. Like 
I stated in my first email, it may simply be time for me to update the 
boot sector again,  but there have been many kernel updates since I last 
had to do it. (The last time, in fact, was almost immediately after I 
installed F7 on this machine.)

The bottom line is that I had to set it up this way in order to get 
Windows XP and Linux to work. Attempting to set up the partitions prior 
to installation of both, then installing one or other other always 
failed for one reason or another. Most notably, after installing Linux 
(with GRUB on the MBR), Windows would no longer boot at all. Using NTLDR 
to load GRUB was the only way I could find to get the two OSes 
coexisting on the same hardware.

Thank you for giving me the instructions on installing GRUB, but I'm 
very nervous about disturbing Windows again, and thus having to install 
two OSes again.
