Hi again..
Here's another possibility.
If you really don't want to see the OS at all then the best bet might be to run it from a USB drive.
Check out this article, it gives you step by step instructions.
I might try this myself, It would be nice to have a backup Windows install.
How to Install and Run Windows 7 from USB Flash Drive
I guess you just plug in the USB drive when you want to boot to the hidden OS.
I have to admit I've never tried this but the article says it works, and my new computer came with a bootable USB drive to run a restore procedure.
