Installing windows 7 on external hard drive

[akshaybona]

I have an old Laptop 120 gb SATA hard drive which i have converted into a portable drive using usb..
i wanted to install windows 7 on this drive but the OS installation prevents me from installing on this drive is there a way around this?
Can install on my main PC drive cause it is a company pc.
Any suggestions or steps would be nice thx

Maybe i'm wrong, but you can not install win 7 on external hard drive.

Not on a usb drive, it can be installed on eSATA external drive, but I don't think the company would appreciate someone messing around with their OS.
