Good afternoon, Paul.

My situation is related but different.  I have a Fedora 9 bootable 
drive, and a WinXP bootable drive, both of which were created 
independently, i.e. when Fedora was installed the Windows disk wasn't 
installed so Fedora couldn't see it and configure a dual boot.

So, how do I set up a dual boot after the fact?

I used to know how to do that with lilo (but, if you asked me now, 
I'd never remember), but I never did it with grub.

Thanks...
