Well, did you do it? Do you even know how? The BIOS has nothing to do with Windows.
If you reformat, all your files will be deleted. You will have to reinstall Windows, all the device drivers, all your programs, then all the updates. It can take several hours. Based on the way you asked the question, I don't think you're up to a reformat/reinstall. Fix your current installation instead.
What is the exact error message on the blue screen?
