I am trying to install windows xp on my external hardrive (80gb western digital 7200rpm) so i could boot off of it later. i am 100% shure that this is possible i just dont know how. it is a usb HD. the first thing i tried was to put in the xp pro disk in the cd rom drive then restarted the system so it loads from the disk. then it asked me what hardrive i wanted to install windows on, i chose the external one then it said that if i continue the hardrive will get erased in order to install windows. then it said that system cant install windows on the drive. what did i do wrong. Please Help!
Thank You. :)
