With all the news about Windows 7 beta 1 leaking onto the torrent trackers, The technicist figured it was time to writeup a Windows 7 netbook install guide. They just installed beta 1 on their HP Mini (deleted the old build 6956 partition), and will update you on how it runs.
What you need
Windows 7 beta 1 DVD image (Google search it)
minimum 4GB USB drive (I used a 120GB Western Digital Passport)
