I have a UEFI system, but I want to install CentOS on a MBR (not GPT) hard disk.
The installation program keeps telling me that I must create an "EFI system partition on a GPT disk mounted at /boot/efi".
I can't find a way to work around this. Is there a solution?
If the installer is doing that then it usually means that the UEFI firmware is either a) not in BIOS compatibility mode b) does not respond in a way that Linux detects or c) the disk is larger than what BIOS compatibility mode will allow.
Otherwise anaconda should default to MBR unless it finds the hardware does not know how to deal with MBR.

I had the same issue back when I installed 7.x on this box. I couldn't find a way around it, so I finally just went with the flow.
I definitely DID have it in legacy mode, or at least the firmware's GUI said I did.
OK I am going with documentation not being right and/or I have been very lucky with my installs.
The only other thing I can think of is that the disk was already formatted to GPT. In that case it has to be EFI. [I had a disk which was GPT partitioned and removing that was quite a challenge as I had done a 'dd if=/dev/zero of=/dev/sda bs=512 count=10' and it still kept coming up as GPT. I believe I had to run a different disk command to really clean it.]
