Yes, UEFI boot issue is fixed.

FYI seems to be a new BIOS Version 0045 with a number of UEFI fixes. I haven't been able to test yet but if someone has had a go please share you're results

I have similar issues. My first issue was, that my mainboard did not boot without a graphics card! Eventhough my i5-3570K has an Intel GPU, the mainboard just stopped at "41". After installing my HD5870, everything worked fine. Second issue: UEFI is buggy. I'm able to install Windows 7 (with GPT-Partitioned HDD), im even able to boot up Windows 7. But the device manager shows an Unknown Device (Z77 Chipset) and the Windows Benchmark fails to complete - which leads to an Aero-less desktop. Ubuntu can't even load the efivars module; which leads to various errors during installation. Deactivation of UEFI Boot solves all errors.

But I did not spend 220 Euros to deactivate UEFI! I bought this mainboard to take advantage of the latest technologies.

Not surprising the UEFI issue and PCIe issue is spreading like wild fire. Imagine you buy a PC and it cannot boot up from the harddisk ! This 2 issue should be Cat 1 priority and they should release some sort of beta bios as a stop gap fix quickly while waiting for verification, authoristaion and signing off of the bios as it takes a long time. But what is the use of verification, authoristaion etc and doing QC on the bios when the bios is broken when release ??? I wonder who approve, test and release all the broken bios !

Rather than simply hoping these issues will be addressed in a BIOS update, I suggest that you (and any others experiencing buggy UEFI implementation) report the specifics officially by logging a case with Intel Tech Support and creating a case. The more people who do this, the higher priority it'll be dealt with. I suspect without fully working UEFI, your GPT partitioned HDDs will be unusable. Let us know how that goes.

I have the same problem like you. I use dh77eb. For bios version 0053, i can create uefi boot entry and save it, but for 0062 and 0071, i can't save it. It seems like the intel desktop 7 serious all have the uefi boot problem. I hope a newer bios will fix this.

Unfortunately UEFI doesn't saeem to work correctly.. it looks half implemented. Using EFI boot manager I'm able to create a boot profile but can't save it. As DislikeYou mentions.. I hope it's fixed in a future BIOS update.

Hi. I also get an error when trying to boot UEFI installed Windows. Also Ubuntu live from USB stick did not want to boot using UEFI mode. Seems a future bios fix will solve this.

Have you selected UEFI in the BIOS settings? Not sure if Linux needs this but Windows does for GPT support so try that and see if it makes any difference (although judging by the thread started by playst, there are problems with the UEFI implementation on this board).

The only way I can boot into bios on the DZ77GA-70K (F2) is if Windows 7 blue screens. The F10 key does work. Anybody else have this problem?
