installing windows another hard drive

Ok I have downloaded Windows Vista , and I would like to intsall it into my second hard drive, which is an internal removeable hard drive, intead of wasting a dvd I deceied to mount the iso virtually. So I did that and ran the install, enter the key and selected the hard drive I wanted vista on, but one thing I noticed when vista starts copying files to my second hard drive, the light does not go on, is this normal, or is it a bug and actually installing on my main drive?
