I was able to install Windows 8 on a Samsung SUR40 for Microsoft PixelSense, I tried to do this some months ago trying installing Windows 8 as a virtual disk but after many test to try having the touch an all other drivers working I failed and I ended up having an expensive table in the office.
Luckily the Samsung service was great and they replaced my hard disk with a new one.
This time I opted for a safest way to reach my goal, I cloned my original 320Gb hdd into a new one so before starting the installation I had two twin hdd.
I’ve to advice that if you are going to try to do this, Windows 8 on SUR40 is totally unsupported, and there is an high risk that you will fail and the result will be a broken SUR40 so if you decide to do it you will to at your own risk, my advice is not to try it, I did it only for testing purpose
Windows 8 on Samsung SUR40 for Microsoft PixelSense
The trick to have all the drivers working on Windows 8 is to launch Windows 8 setup from the original Windows 7, with this approach Windows 8 was able to find all the needed drivers alone, at the end of the installation all the devices was recognized correctly by the new operating system,
Because of the HID usages owned exclusively by Windows 8 all the Surface input stack will not work but the standard WPF input stack works fine.
As I already noticed on my Dell ST220 because of the frame containing the lcd panel swipe gesture from the bottom or top edge of the screen to get app bars, from the right edge to get system commands and any other swipe gesture that that needs to be started outside the touch area are uncomfortable
Another consideration is that many Win8 apps (especially third party apps) are designed for single user and often just single touch. Not all developers even consider multitouch, let alone multiuser. This leads to a poor experience with multiple users but I will discuss about Windows 8 user experience on large format displays and the Surface SDK in another post soon.
