Booting From an External Hard Drive

Hey guys!

I want Windows 7 to boot from an external hard drive instead of my computer's built-in HD. Is this possible? Also, what do I need to do in order to achieve this?

I know it's possible, but it's fairly complicated.
I believe it has to do with creating a BARTPE environment.
Anyways, it's the same idea as installing to a flash drive.

if you look at the stickys for booting the installer from a usb drive, id reckon you could get an installation working the same way.

do the prep work on the usb drive first, format it to ntfs and copy the bootsect from the dvd, now have it plugged in when you run the installer from the dvd, windows should recognise it as a bootable hd and hopefully list it as a available destination for installation.

best of luck.
