If it's winxp then there is no more DOS. those days are gone.
You gotta get winxp cd. Insert it into cd rom and restart. If it does not promt you to boot from cd, then you need to get into bios and make your cd rom a priority bootable device. then restart again, finally boot from cd. on the cd go to "command prompt" section. Now you can run format commands and such...
If you want to just have a clean reinstall of windows, then you can go into installation mode right away, and it will offer you to format your drive before installing windows.
Good luck.
