You should be able to use a retail version of Windows 7 to do your install, ie, download the latest ISO image with SP1 and then install it.
NOTE: You may have to call MS to get it activated using their automated voice system. (I've used it and it's quick, about 5 minutes, and works. Sometimes a human may come online to help out.) Explain the situation and MS tech support will help out. They are there to help, not to send the storm troopers after you.
Be sure to get the ISO with SP1 to save you the grief of a large upgrade download afterwards.
Your notebook more than likely had Home Premium installed on it. Go to this link here at this forum and you'll get the latest ISO image download.
