[Users] Still unable to boot in system with UEFI

Hello: Recently I downloaded the ovirt stable node image. According to releases notes since 2.2.2 UEFI installation bug has been fixed, but I still can't boot from my server with UEFI. Ovirt installs without problem, but when the system reboots nothing happens, the system don't boot. Then I try to boot with super grub disk 2 live cd, it detects ovirt installation and boots the system. I think that still there is a problem with UEFI in certain hardware: Mi system is a IBM blade center HS22 7870 Can anyone confirm problems with UEFI in 2.2.2 version? Thanks Federico
