In summary, here is a list of things that is "good to know" when installing Windows 7:
* Load bios defaults and disable audio (disabling of audio is necessary if the installs stops during the boot - I had one success and one where this hack was needed) (thanks Jethro)
* Make shure that the usb key is set as a boot device. Mine where for some reason excluded in the boot list.
* When installed, download the optimized Intel driver from:

The driver is installed by updating the driver in "Device Manager". The setup.exe will complain about unsupported OS.
* Set output to "Digital Display" instead of "Cloned" (thanks ender)
* A driver for the missing AVR309 can be found here:
