Re: How to remove operating system from Harddrive ?
Another solution would be to download and burn PCLinuxOS MiniMe, boot it, and use "DiskDrake" to remove the partitions. There are other live discs that have partitioners. eLive is good too, it has GParted. Knoppix is the best for older computers, and it has QTParted on it (Last time I checked...).
