Can I create a Windows Live installation that runs of an USB stick?

Question

Is it possible to create a usb bootable version of Windows 7 just like ubuntu??

I mean boot the actual operating system and not the installer from a usb?

Answer 1

Yes, you can using WinPE or BartPE

This is normally used to create Live CD's, but you can achieve the same result using a USB stick.

Here's an example of a BartPE installation for Windows XP

Note that the performance is likely to be pretty crappy unless you use a really stripped version of Windows.
