How to remove boot option?

I never even successfully installed Kali or booted to it. But of course I have more trouble than success dealing with Kali. Broke down and just decided I am forced to use 4GB USB to Live boot and then partition/install Kali.

THE PROBLEM:

I cannot figure out how to remove the "Debian..." boot option when my ultrabook boots up. It's stuck on the windows boot manager screen.

I unmounted the Daemon Tools drive and the only drive I have visible in my directory is C:\

How do I remove the option because with it there it just keeps trying to install, which I can't do without a CD-ROM. Even with my Live USB plugged in, it won't allow me the option to Live BOOT. It just automatically tries to install which requires CD-ROM.

I'M PULLING MY HAIR OUT OVER HERE!
