So everyone has heard that with the upcoming Windows 7 you can install via a USB stick. Well it is not just that one operating system; Win XP, Vista and Windows Home Server can also be done this way. Sure others can also be installed using this method but I have not tested it.
So how hard is it? Not hard at all. There are many links on the internet if did a search but a handy little tool has come to light. It is called “A Bootable USB”.
It is best that you use a USB that is 4 GB or greater but on some of the OS installs you can use smaller ones. Be aware that some USB sticks that I have tried have just not worked.
This utility is so easy to use; The Utility, a USB stick and the DVD or ISO image of the OS. The utility can create a bootable in a few minutes. You simply specify your source (DVD or ISO) and click “Start” (“Start DVD” or “Start ISO”). Upon completion, you’ll have a bootable USB drive which you use to install your new OS.

I was able to install Windows 7 Pro with this utility with relative ease. There are actually a few steps involved, but it is not hard to figure out. The one thing lacking in the little tool is a progress bar for all the steps. The only one (I can remember) having a progress bar is the format phase. Other than that, it seems you just have to wait it out until you get alerted the process has been complete. Thanks for posting this, I was able to get W7 installed easily with this software.
