Windows 7 is available for download for testing purposes only. It can be made to work under VirtualBox OSE though getting network, sound, and Guest Additions requires some additional steps.

Download the iso and print or simply copy/paste the product key to some place safe.

Verify the download:

$ openssl md5 7000.0.081212-1400_client_en-us_Ultimate-GB1CULFRE_EN_DVD.iso f9dce6ebd0a63930b44d8ae802b63825

Install VirtualBox:

sudo apt-get install virtualbox-ose

Get network and sound working using John Paulett’s instructions:

On Ubuntu: cd ~/install_files wget http://www.amd.com/us-en/assets/content_type/utilities/V4.51.zip unzip V4.51.zip -d driver mkisofs -o driver.iso -R -J driver Back on the Windows7 [Running] VirtualBox OSE window: Devices => Mount CD/DVD ROM => CD/DVD ROM image Add; navigate to and select driver.iso; Select Windows Start button => Control Panel => All Control Panel Items=> Device Manager Right click on Ethernet Controller => Update Driver Software => Browse my computer for driver software; Browse; Computer, D:, WinXP_SignedDriver; OK; Next; Close [Wait a minute, and Windows7 will automatically start downloading and installing updates; Device Manager window will flash numerous times; eventually the flashing will stop with only the “Base System Device” indicating an issue; ignore] Windows Start button => Shutdown => Restart

Audio will now work, but for some inexplicable reason, the screen resolution changes to 800x600. Right click on the background; Screen Resolution; chose from one of the available resolutions (presumably there will be more and better choices once guest additions are updated for Windows 7); OK, Keep Changes
