I have two hard drives in my computer. The 40GB Western Digital has Windows XP on it and it is currently set to be the Slave. The 20GB Western Digital has RedHat Linux installed on it with GRUB on the Master Boot Record (MBR) and that hard drive has the jumper set as the Master. When starting up it comes up with the GRUB prompt to choose either "Red Hat Linux" or "Microsoft Windows XP". If Linux is chosen, everything works fine. If Microsoft Windows XP is chosen, it echos the code in the /boot/grub/grub.conf file (under the Microsoft Windows XP section) and just hangs at that black screen. My grub.conf file is as below...

default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-8 )
[TAB] root (hd0,0)
[TAB] kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi
[TAB] initrd /initrd-2.4.20-8.img
title Microsoft Windows XP
[TAB] rootnoverify (hd1,0)
[TAB] chainloader +1

I am minimally experienced with Linux and am trying to learn. Any help that you can give me would be greatly appreciated.

Welcome to LQ.

Windows likes to tbe the master - you can fool it by using an entry like:
title Windows XP
rootnoverify (hd1,0)
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1
