I am trying to install Windows 8.1 on an existing partition. I can’t format it because i have like dozens of GBs of data there. I receive this message when i select the partition. I am installing the system from DVD in EFI mode.

The error occured because the disk did not have an EFI system partition. I moved all data off the disk and let Setup create the needed partition layout.
Another scenario in which that message kept popping up for me was when I had several hard drives in my tower. I unplugged all but one, and then it would finally get past that error message. – Gabe – 2013-12-06T04:01:44.010
