Windows 7 wont boot without external hard drive turned on?

I just restarted my PC and i kept getting erros regarding hardware, at first it would just hold at updating dmi pool , after i reset the bios to fail safe defaults it would then give me the I/O error. I noticed my external drive was turned off and I turned it on and windows booted fine. Is there a connection here i can disable?

Windows is installed on my SSD drive not my external.

Try starting your PC with external HD unpluged.

If you can't boot up with external unplugged, then plug it in and post back a screenshot of your full Disk Mgmt drive map and listings, using SNipping tool in Start Menu.
