I installed Centos 5 on an external usb drive and everything went
smoothly but now when I boot without the USB drive attached it
displays GRUB in the upper left hand corner and just sits there. If I
plug in the USB drive and tell the computer to boot from the USB drive
the GRUB boot menu displays and I can select either Centos or my XP
installation. I don't really need the GRUB loader and need the laptop
to boot without the USB drive attached. What do I need so either GRUB
is on the C: drive where my XP is or can I get rid of it and get XP
just to bootup by default without me having to select boot from USB
device and selecting the XP.

Thanks,
Chris

Where, exactly, did you install the grub bootloader? On the USB drive,
which is seen as a SCSI drive? And what is the boot order set for your
drives in your BIOS? (Removable storage first, internal drive second
would be good).

I'm afraid that you put grub on your Windows drive. You're going to
need to boot into Windows and reset its boot loader manually, or use a
Windows installation CD if this is hte case, but there are dozens of
pages like this:

Sounds like he put the Grub bootloader on the Windows drive but the Grub
second stage on the removable drive.

Yes, precisely. This will typically show up in the contents of '/etc/
grub.conf', which is actually a symlink to /boot/grub/grub.conf. Be
careful to edit /boot/grub/grub.conf, and reset where it is installed
to. How to boot Windows on its own, and the Windows drive, after that
is another story.

One can usually boot from the removable media by selecting it from the
BIOS or from the BIOS screen, and leave the Windows system to boot on
its own by default as appropriate.
