Problem is, on my "black screen after a fresh installation with just a cursor", pressing CTRL+ALT+Del does absolutely nothing.
Microsoft suggests starting up in Safe Mode, but to do that, errr, I need to be able to "hold the Shift key down while you select Power Power icon > Restart." Errr yeah... I don't have any kind of menu, I can't do that.
And if I shut down my computer and restart it.... same thing. Hitting during bootup F8 does nothing, I just end up with the black screen of nothingness.
One interesting thing: if I do SHIFT + CTRL + Escape, the cursor turns into a "Please wait + pointer" cursor for about a second. But still nothing appears.
But - I found a ridiculous solution (you'll love this).
I'm using an Asus ultrabook, and nothing would make the screen display anything. But then I attached it to my monitor. Actually, I just plugged in the cable, I didn't actually use my monitor. At which point, the Windows "How would you like to set up?" screen appeared (personal use, or setup for an organisation?"
And now, I could now remove the cable, and my ultrabook's screen was alive and kicking again.
Microsoft... be careful. You're becoming as unstable as Apple....
(This is the bit where an MSDN confirms that "This is not a bug, but thank you for your feedback.")
