You can download an OEM windows disk or call up your Hardware manufacturer for it if it wasn't provided with the computer (I'm not a 100% sure on this.)

As long as your laptop shipped with windows you can install either 32 bit or 64 bit of the same version (oem) on the same computer.

Yes it's a huge pain in the ass not the easy one step process implied above.
