Your hardware appears to be unsupported + Failed to authenticate the disc

I recently received a physical copy of ME2 for Christmas and just got around to wanting to play it. My laptop does not have a disk drive for some unknown reason so I had to install it on an external hard drive on another computer. When I first tried to start it up I get a error message that says "Your hardware appears to be unsupported. The game will continue, but you may experience reduced performance or instability." After looking up that error I decided I would deal with it later in case anything does go wrong. After that, another error came up that said "Failed to authenticate the disc. Please insert the correct disc and try again." As I stated before, I don't have a disk drive so I can't put in either disk. Is there any way around this or am I never going to be able to play this?
