I am fixing a desktop computer for someone and need to reinstall Windows. I need to know whether to install 64-bit or 32-bit Windows. They accidentally formatted the hard drive.
Normally I would just go into the hard drive and search for a
Program Files (x86) folder as described here, but clearly that will not work in this situation.
So, is there a way, possibly with a Linux Live CD or maybe by just looking at the processor / motherboard, to tell if the computer supports 64-bit?
