This is for mags but almost everyone will find some use for it.
Firstly download microsoft virtual pc from here
anonym.to - free dereferer service
Then install it then open it up. Click new and then give your machine a name.
Then you will come to an os selection. Go down to other then click next. You then have to select the amount of ram you want to give the machine. Once set click next and give it some hard drive space, i recommed virtual.
Then click next and finish it.
Start up the machine then click cd at the top and mount the iso or cd. Click Action > Reset and your OS should load.
