Computer is a new Dell which did not come with a Windows XP disk (OS was pre-installed). Dell instructions tell you to use system restore, Dell restore or IF your PC came with an OS disk you can re-install Windows. Dell restore restores your system to it's original state. The only trouble with Dell restore is you lose everthing that you did after you got the PC. Dell says you do not need an OS disk and if you WOULD need an OS disk in the future they will send me one if they determain I need on. You don't even get an owners manual. The 134 page manual is installed on the computer. PC also doesn't have a floppy disk.
Hard drive doesn't have a seperate partition with the OS on it. There is just the C Drive with no other partitions.
Dell 820 D (Dual CPU) 2.8 GHZ, 1Gig Memory, WinXP MCE,
250 GB Hard Drive, 256MB ATI Radeon X600SE Graphics Card, no floppy drive.
