So you have a notebook and want to install Windows 7, how the f… do you do that you think – there is nowhere to insert that damn DVD?!?!
Well why not install via a USB pen?
So grab your USB pen and visit here; http://store.microsoft.com/Help/ISO-Tool
A few things you will need though, 1 USB pen (aprox 5 gb) and to convert your DVD to an ISO file (the latter is rather simple, there are numerous utils that can do this – google it).
An alternative to this is; http://wintoflash.com/home/en/ (should be able to grab the data from the CD/DVD and should work with other versions of Windows as well).
I have not yet tried any of these, but gotten them recommended.
