What is your main reason why you want to make bfgminer work?

If your reason is all about mining Bitcoin with your PC then it is big no you can't mine even you can make bfgminer work.
You need ASIC machines to be able to mine Bitcoin.

Then read this below if you decided to mine Bitcoin with ASIC machines.

- First time/Small miner reference for getting started.

Then read this where to buy

- Current List of Competitive Hardware
