   6. Mount the Windows 7 beta iso using Daemon Tools or similar.
   7. Navigate to the boot directory
      cd E:\boot
   8. Using bootsect, we’ll make the USB drive a bootable NTFS drive, ready for a Windows 7 image (my drive was labeled G):
      bootsect /nt60 G:
   9. We are finished with the command prompt now, so you can close it.

Step 2 – Copy the installation files from the mounted Windows 7 iso to the USB drive.

Step 3 – Install on the Netbook

   1. Plug in the USB drive and turn on the netbook
   2. On start up press <F12> to select the bootable drive
   3. Select the USB drive and press return
   4. The netbook will boot from the USB drive and the installation will begin
   5. Install as normal.

I hope this helps someone, and if not, at least I’ll know where to look the next time I need this information. :-)
