I have a Mac Mini with Intel Core Solo processor.
The HD of this computer was formerly part of a PC, and so Windows XP was installed on it. I've successively moved the hard disk from PC to a Mac. All works pretty well, Windows XP starts without any problem. I would now install Ubuntu on this Mac. Alas the DVD drive is out of service, and so I have to find alternatives.
I've thinked to use a pen drive and start installation from this device. Anyone have experience in this and can tips the best?
