Attempting to install non Dell OS on a Dell laptop will always be somewhat problematic.
Drivers will be hard to find.
Anyway if you have a full 2K CD with proper key and want to install it just run KillDisk first.
KillDisk will totally remove all data from the laptop.
Active@ Kill Disk Hard Drive Eraser. Low Level Format.
Neither 2K nor XP use DOS per se. KillDisk is FDISK plus. Total erase.
Then install 2K (assuming a full disk with valid key).
Afterwards you will need to try and find specific drivers.
