First of all, I cannot overrite the Ubuntu OS with a bootable Windows XP OS disc (extracted .ISO files). i was also unable to format the drive from inside of UBUNTU; i do not have an authentication code. Now, trying to format using cables to my PC: IDE to USB with molex power connected to electricity (cables to go); can't get the drive to be recognized. The drive is still in the PC but the cables are disconnected from the HDD to the motherboard. i am going to remove the HDD from the PC all together, then try to connect it to my PC to format it (IDE to USB with cables). this has worked before, but it is not happening today. Is there any way i can overrite Ubuntu with Windows XP or at least format the HDD without taking it out of the PC to format it through my desktop? if it will show up under Disk Management or on the PC at all.
