Changing this mode can cause issues. It is not a problem by design. That is, I expect such but without writing a book on UEFI... Plenty on the web so keeping it short. Expected.

Hi guys i Don't know if this is the right place but anyway ... I recently bought a Motherboard Gigabyte GA-X79-UP4 and in the Uefi i had this configuration to boot legacy, uefi mode and combined. The problem is that when i use uefi only the drives are not shown in the boot menu (but are shown in drive list) and i get message there is no boot device, when i am in legacy or combined mode there is no problem I am just interested in this problem did some one experienced it two the drive are formatted in GDP
