I find folk spend a lot of time and money restoring Windows when they've lost the media or wiped the drive. Install Ubuntu and move it out.
Apologies if this has come up before. I'm selling my old desktop and read that eraser was the best program to clean it up etc so I downloaded and ran eraser but now I cannot boot my computer.Ive no boot cd and tried everything I could to even start in safe mode etc but have no luck. I'm a novice computer user so bear with me please.
