Windows 7 - Win 7 Bootloader - multiple drives

Hi,
I have searched around on ths forums but can't find an answer.
My work laptop that has pointsec (disk encryption) on it, which is the first thing that loads.
If I was to install Windows 7 onto a external usb HD, would it overwrite the bootloader on the internal laptop HD?
Should I go into the Bios and try to disable the internal drive (not sure i can get to the bios)?

Thanks
Satpal

Welcome to SevenForums schander
Not sure if you can do that, I would love to see the documentation if I am wrong. Good luck to you in finding your answer. Hope that you enjoy your time on 7 and SF.

Windows 7 will not install to an external drive. MS has struggled mightily to keep it off of them, as their OS would then be portable and carried around to any computer.

The only tutorial I've seen for doing this is for XP and it is extremely complicated.

The questions you ask need to be answered by your IT dept. at work, or whoever maintains that internal encryption. Any attempt to disconnect in BIOS setup could brick the laptop.

Thanks for your replies.
I will try and talk with work IT, but there worse than useless..... and in India....

Thanks
