Windows 7: installing Windows 7 from a USB Hardisk

installing Windows 7 from a USB Hardisk

hello, if I asume that a machine can boot from a USB hardisk, is there a way to install windows 7 from a USB harddisk without having to format my USB Hardisk? I read a tutorial for installing windows 7 from a USB Key, and I assume it works with a USB Hardisk too, but since the drive size is 250GB it would be crazy to format all of that to create the ISO image.. would it be possible to create let's say a small 4 GB partition and make it active/primary and write the ISO to that partition, and boot from it? thanks!

I believe it is possible. Very good question. This should get the job done for you.

Tip: make your PDC 2008 (or any) USB hard drive a bootable Windows 7 install disk - istartedsomething

Let me know if it works. It should. I don't care much for mounting (just because I've only done it once) I would just buy a 4GB flash drive.
