Installing Windows 7 from a USB flash stick
Windows 7 is available now for MSDN and TechNet subscribers as well as members of various other Microsoft programs. It will be made available on May 5th for the general public to try out also.
The method of installation is to burn the .iso image file onto a blank DVD disc. You can boot from the DVD you have made, or you can run it from within an existing Windows installation. Yet, if you do not have an optical drive on your computer of choice then booting from DVD is not really an option.
You can extract all the files to a USB stick using a free open source program like 7-Zip. This allows you to run the Windows 7 setup program from your DVD-challenged computer by plugging in the USB stick.
