bfd, yes that works for me too. At the final stage of installation (just prior to entering the product key) the screen went blank, except for a 1-pixel row at the top of the screen. It is not possible to boot into Safe Mode at this stage - you get an error message saying safe mode cannot be used until setup is complete. But rebooting and pressing F8 and selecting "Enable low-resolution video (640 x 480) allows installation to ask for the product key and complete. However, if I just rebooted again after that I got a blank screen again (no 1-pixel row at the top this time!). To fix this, I booted again specifying low resolution mode, then went into the display settings. The default setting was 1280 x 1024, but this did NOT work and resulted in a blank screen. Setting it to 1280 x 960 works fine.
Follow up from previous post. Now W7 is up and running, doing a Windows Update found a driver update for my onboard Nvidia Geforce 6100 graphics controller which now allows the correct resolution of 1280 x 1024 to be used.
