BSoD after installing Windows 7 on my spare hard drive?

Alright, so I have a primary hard drive that I have my main OS (Windows 7) installed on, and i had a spare hard drive. I decided to install windows 7 on that hard drive also, but after I went through the entire process of installing it, I went back into my primary hard drive and it wouldn't boot! I don't know if MBR is messed up or what, but when I try yo boot into it through the default Windows bootloader, it says that there was a problem and that it shut of the PC so that there would be no damage to it... Please help! I need to get access to that hard drive!! Thanks :)

You can not dual boot Windows 7 HP x64 & Windows 7 HP x64.
You can dual boot Windows 7 HP x64 & Windows 7 HP x86.

With both HD's plugged in, please post back a screenshot of your full Disk Mgmt drive map with listings using the Snipping Tool in Start Menu.

Can you see the other HD in explorer via Computer?

If Win7 won't boot now, try changing the HD set first to boot in BIOS setup. If it still won't boot, download and burn to CD free Partition Wizard bootable CD, boot it and post back a camera snap or write down the listings on each partition on both HD's.

i just decided to remove my space hard drive, and fixed the boot up on my main drive with the windows dvd, so it's alright :\, 2 hard drive just causes too many issues for me right now, so i'm good with one for the time being
