You can call and pay them 40 bucks for a copy of the OS. 9 times out of 10 people fail make copies. When the system boots it asks you if you want to make copies but people are too excited to get in and start screwing around with there computers they tell it no. When the computer crashes or worse the hard drive fails and then there stuck without the OS. There are some OEM disks out there that work with the Dell keys and you can install it from there. Just DL the drivers from there web site and you should be good to go. If its XP Pro and you pay for the shipping I could send you a legal disk for dell machines. Our company just ordered a crap load of dells and we put our own image on them and toss out the OEM disks.
