The OS X installer requires GPT partitioning.

Both disks are GPT.

It doesn't appear to be the case (no EFI partition on the first one).

Cause on the first one isnt any system for now. And it was added when system was already installed. Is that problem ?

It should still have an EFI partition.

So why is on that disk no EFI partition ? Can be EFI partition created somehow ?
