I actually saw that page when I was searching on the internet for how I could do this. Though other than that all I could find was tutorials telling me how to boot into DOS with a floppy disk, which I can't do since floppy disks arent available... I know that optiplex gx260 can support USB booting with a BIOS upgrade. It doesnt support it as is, I tried. As for booting with the grub thingy, the OS I'm currently running on the Optiplex is Windows XP Proffesional. I wouldnt mind learning more about that method you mentioned.
