I'm fairly new to Linux and have a question:

I recently installed Red Hat 9 on a 40 GB drive (1st drive is 40 GB XP)

I bought the 2nd drive so I could work on it independently from the XP OS.
During an installation a few months ago, I was able to disable the XP drive
in the BIOS and enable the 2nd drive whenever I wanted to play with Linux.

Today in the Linux setup I disabled the boot loader and also deleted the DOS
boot from the setup. Yet, the GRUB still appears. The only way I can get
into either the XP or Linux OS is enabling both drives in the BIOS. If the
XP drive is enabled and the Linux is not, it's giving me a GRUB Hard drive
error. If the Linux drive is enabled and the XP is not, it goes straight to
the GRUB dos prompt.

Is there a way around this?

The Linux setup doesn't let you change which HD the GRUB is installed.

Many thanks in advance.
