William, thanks for the great information. I have a tablet PC with no CD drive or floppy disk and I can't intall from a usb CD drive. I installed XP onto the laptop HD using my desktop, then removed the drive before re-boot. I then reinstalled the HD back into the laptop and it booted to Windows and it started the setup. It then prompted me to insert Disk 2 with the tablet PC files on it. I have this disk but can't use it during setup for lack of CD drive. I can't go any further with the setup and have to cancel out of it. Any suggestions?
