i don't think it will work! you must make the pendrive bootable, how are you supposed to do that?? if there is any solution guys, please post!

Yes! It is absouletly possible! you can install windows 7 from a flash drive to your laptop! but first you must make the flash drive equipped with windows 7 installation and boot files. so you need a computer with windows 7, a dvd drive. windows 7 dvd, a 4gb flash drive. now goto command prompt and type :

xcopy e:\ f:\ /e /f

here e: is the DVD drive and f: is the flash drive drive nothing else has to be done! now go boot ur laptop with the Flash Drive!
Have Fun!

I've just tried the xcopy thing and I get this error, EVERY time...

D:\>xcopy e:\ g:\ /e /f
File creation error - The parameter is incorrect.

Unable to create directory - G:\

1. I am running Win7 beta (official key)
2. I have an 8GB mem stick
3. I have a Win7 DVD.

Help, thanks.
