Reboot and select proper boot device

[Drunken Deriver]

I have a prostar laptop that I got a few months ago. Today I was messing around with Windows a bit (In place I probably should not have) and when my computer rebooted it gave me an unsigned boot driver error. Okay, I'll tell it to ignore that. Wasn't an option to do that anywhere. After rebooting a few more times I get this error "Reboot and select proper drive..." and now it won't do anything. It won't POST, won't let me access BIOS, nothing. Hit the power button and it just shows that. I tried taking out the second HDD and trying it with only the m.2 SSD and booting but same error. Any help would be very much appreciated. Here are the specs:
i7 4720hq 2.6 ghz
gtx 960m
8 gig ram
1TB HDD + 128 GB SSD (primary)
Windows 7 professional SP1 x64

I'd try repairing with a Windows boot DVD/USB, if you can't even BIOS.

Well, I don't have a DVD but I have a flash drive. That didn't work. I also tried without any storage devices at all and same problem.

Edit: I got to the BIOS!!! Im so happy I nearly teared up. I jut mashed fn keys until it came up. I'm installing windows 7 on a backup partition now and using that to repair the other. Not 100% how to do that though. Any thoughts?

After reading this, I'd suggest you double check every HDD/SSD connection just to be sure. It migh've still been a corrupt Windows or something, so I'll wait for you to say how your repair went.
