Easy one to remove.. Look dead center in front of the laptop and you will find the hard drive caddy filler plastic door. Two rubber plugs from the bottom (the center ones) Under these two phillips screws and it will slide out. You will need a 2.5 - 3.5 drive adapter and will also have to remove the drive adapter block from the hdd.. (Small plastic push on block that covers the 40 pins to connect to systemboard).. good luck!
(Hard drive is probably toast but you could try Fixmbr as well as fixboot w/XP recovery console)
