Can I make a bootable drive for mid 2010 MBP with a Windows computer?
Have you tried Command+R when booting to access your recovery partition (if Yosemite created one during installation)? That would be your easy get-out-of-jail-free card.

Otherwise you're looking at seeking the help of some kindly Mac owner who has disc images of the original install discs (or a retail Snow Leopard disc). If you put some contact details in your profile I have a friend who may be able to point you in the right direction. Once you have a disc image you can burn a disc off with any Windows disc-authoring software supporting .ISO files, which is pretty much most of them.
