LinuxQuestions.org - win xp + redhat 9.0 GRUB problem

I had win xp pro installed on my machine and had just installed an additional hard drive. I decided to install redhat 9 on the new hardrive. I think I installed the GRUB bootloader and selected

/dev/hda Master Boot Record (MBR)
and not
/dev/hdb1 First sector of boot partition

which were the two options.

Now when I start up right after the dell logo, i get a screen that just says

GRUB

with a cursor blinking right after it. it does not noticably respond to any keystrokes except ctrl-alt-del at which point it restarts the computer.

If anybody can tell me what I did wrong, and why, and how I can fix it, that would be great.

i also tried to repair the MBR using the FIXMBR command in the recovery console of win xp. But I cant even get to the console because it just wont accept my admin password for some reason.

thanks in advance.
