I wanted to take a sneak peek at Windows 7 so I thought of installing it. I have Windows Vista on my laptop which came pre-installed through it. I didn"t want to mess via it.

You watching: Pwboot

So I created a partition (20 GB) in my USB exterior difficult disk and tried to install Windows 7 on that partition. But once I booted from a Windows 7 DVD and selected the taracquire partition on USB hard disk, it sassist it cannot be installed.

Is there any means to install Windows on an exterior USB tough disk?
