Things You'll Need
Instructions
Convert the game image files into ISO files. You will need a file conversion plug-in that can be downloaded for free from the internet. The files will need to be run through the conversion software to change them to .iso files. This will have to be done on a computer using the original game files, which may require you to use a different computer than the one that you want to play the game on -- unless the computer that you want to play Medal of Honor on can accept the game software in its original format, on CD.
Copy the game files on to the USB drive. Make sure that all of the files transfer. Insert the USB drive into the computer that you want to play the game on.
Wait for the computer to recognize the USB drive then execute the game files. At this point you have the option to either play the game directly from the USB drive or to load the game files from the USB drive on to your computer's hard drive.
