After Parallels install, can't boot Windows in Bootcamp

[Sincell]

1. I installed Windows 7 using Boot Camp
2. I installed Parallels and used the Windows 7 boot camp partition

All worked great.

But now I want to boot in Windows 7 using Boot Camp (not Parallels) and I can't figure out how to do it.

It seems to ALWAYS boot Windows using Parallels now like Parallels 'took it over'

Is it possible to select to boot Windows from boot camp once in a while instead of always in Parallels?

1) I installed Windows 7 on a Boot Camp partition and everything was working perfectly.
2) I wanted the ability to access Windows while I was in Mac OS so I installed Parallels 9 and selected the option to use the existing Boot Camp partition. During the setup process there was a notification that Parallels was 'upgrading Boot Camp' or something similar.
3) Windows is working fine in Parallels however for heavy lifting stuff such as Autodesk Inventor I want to continue using Windows through the Boot Camp interface.
4) This is no longer possible. I don't get past the point where (after pressing the option key at startup) I choose Windows and press enter. It just hangs.
5) It's very frustrating and I am losing valuable working hours. I have tried deleting the pvm file in Documents/Parallels in the hope that I can go back to using Boot Camp only but unfortunately it no longer works.

Can any one help?
