Sorry for the Urgent bit but it is.
I need to completely uninstall Mint from my son's PC. It is the only OS on there and was a relatively new hard drive. I have done searches for info but not come up with anything. The PC has no floppy drive to run Fdisk and all i have is the Dell restoration CD. When i put the Cd in the PC nothing happens even after reboot as it boots to mint as usual.
I am a computer numpty so please use idiot speak for me thanks!!
