Dual-Boot Win 7 & Win 8 - Boot Failure

I currently have two drives in my laptop:

1. 128GB SSD in the Optical Drive space with a clean Win 8 installation.
2. 750GB HDD in the standard slot with a Win 7 installation.

Right now when I start up the computer, I get the option to run either Win 8 or Win 7.

I actually want to use the 750GB drive for something else, and thus want to remove it from the computer - which is easy enough. However, when I remove the 750GB drive suddenly the computer will not boot anymore. It gives me a "no bootable device" error.

How can I get my laptop to boot from the 128GB Win 8 install in the Optical Drive slot?

The computer is a HP Envy 14 Beats Edition 1260se.

Thank you

If you installed Windiws 8 with the 750GB HDD in the standard slot with a Win 7 install, the boot file for Windows 7 & 8 are on that HDD.

How might I move the boot file for Windows 8 to the 128GB SSD in the optical slot?

As Windows 8 is on the 128GB SSD in the Optical Drive space, you may need to reinstall.

Can you post a screen shot of Disk management? (with both drive.)
