Should be possible, all the bios does in this case is determine the boot order, so if you want Linux to boot or drive a or if you want drive b to boot first. So what you do is plug one drive in and install Windows to that drive. Then plug in your second drive and start installing Linux, when it comes to the drive screen, select the drive that is empty. After you install everything, go to your bios boot order and make it boot into what ever drive you will use most often. Or you can do something called a dual boot. This is when you have 2 operating systems on one hard drive. Thing is, you have to select which operating system you want every time. Hope this helps.
