Installing Via USB Or SD Media

So Windows 7 beta is out the door and you are ready to begin your beta experience. Over the next few months there will be additional builds for Windows 7 (x86 and x64) as well as Windows Server 2008 R2 and that leads to a lot of installs and a lot of DVD burning and useless DVDs as soon as a new build is out. So why not install from USB or whatever other removable media your computer can boot from? Insert your removable media into a Windows XP or Vista PC and run the following commands from an elevated command prompt.

diskpart list disk (find the disk number for the removable media) select disk # clean create partition primary select partition 1 active format fs=fat32 assign letter=y (or any free drive letter) exit Once that is complete mount the ISO and run the following command.
xcopy x:*.* /s/e/f y:

Where “x” is the drive letter of the mounted ISO. Once complete boot off the device and install the OS. When a new Windows 7 or 2008 R2 build is released, simply delete the contents, rerun the xcopy command and you are ready to go again. As a note this also works for Windows Vista and Server 2008 but you already figured that out
