On a new GPT initialized disk (second PC disk) I created a FAT32 partition using gparted. I want to use it as an EFI System Partition so I flagged it as boot. After that I checked the UUID using the gparted “partition information” option and it reported: 09B1-97A5. As far as I understand it should be C12A7328-F81F-11D2-BA4B-00A0C93EC93B.

I also checked my running operative system disk (Ubuntu 14) and found that Gparted reports EB78-9AD2 for my actual boot partition UUID. What exactly is gparted reporting as UUID on my EFI system partition and why it doesn’t match with the expected C12A7328-F81F-11D2-BA4B-00A0C93EC93B ID?
