Ran into this error when installing Win 8.1u1 on a new low-end laptop via USB key…

The complete error was:

We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files

suggests simply using diskpart – but that didn’t work for me.

I was about to use a DVD for the install….(which would have meant trying to find a DVD…. for which I would need a tardis in order to go to when DVD’s were actually used) – when I simply unplugged the usb key, refresh, error…., plug the usb key back in, refresh – all good.

Now that’s some absolute whackiness…..
