Anyone else been struck down by this?

Installed a bunch of updates a few days ago, shut down the computer last night and rebooted to a black screen. Tried to system restore - but no restore point was made. No idea why one would not be made, it was last time I had to roll back after a dodgy update. Can't boot to safe mode or low graphics mode, will try command prompt tomorrow when I get back home.
Second time this year PC has failed to boot after windows updates!
