Using BIOS 1301, but this was an issue with previous versions as well. Trying your "unplug" method, worked, but only for a few boots. Then I get stuck on the BIOS splash screen again. Interestingly, I then just have to turn the PSU power switch to off and right back on ---- then the machine boots as normal. I don't understand why the PSU "power-cycle" always fixes the issue (even if temporarily).

Thanks for the note --- mine always hangs with the "HDD A0 ---- Detect HDD" message.

I had been using the same system with a different mobo, and never had this problem; thought this board would be an upgrade 😞 Maybe I just got a defective board or something? Either way, this coming week I'll be taking this system apart and going back to my other mobo.

What drive do you use?

I'm using a Samsung 960 Pro M2 . I have it attached to the board that plugs in next to the RAM slots.

Got the same problem. Once, twice, sometimes more often a week, after having shut down the PC over night, the next boot the system hangs during boot. Error code is mostly different, I think "detecting HDD" is one of the last to hang with. Turning off and on the PSU, fixes this and my system boot normal. The strange thing, I get no report for a boot error with go to BIOS, which normally happens when the system got problems. Before doing the PSU trick I had another approach. CMOS reset, first boot hangs with the same symptoms, second one boots in the BIOS with the F1 error prompt, load settings and boot normal. I still have the impression, this platform is not running well, at least with the Intel Core i9-7980XE. And maybe there are not enough people using this CPU to get this ever fixed 😞

Never say that: "I still have the impression, this platform is not running well, at least with the Intel Core i9-7980XE. And maybe there are not enough people using this CPU to get this ever fixed"... You just have to howl Every body on this forum pay for a premium board, best of the best with all you want on it, all last connectivity etc... marketing way... Bios 1301 is here maybe the 10th and a lot of issues are still here! Begun to be bored by motherboards and components manufacturers who say pay now and maybe one day we will finish the job... Can you give me an example of job where you can do that? You don't buy a star citizen ship or à beta version of something but a premium product normally finish for a workstation, HEDT High End DeskTop not MWMN Maybe Work Maybe Not... I know Bios update are here to optimize with new components and some compatibility optimisation but 960 pro are out since 2 years, TBT3 since 3 years (i refer to other thread sorry) and there to much bugs with other things, check this forum... It's not new component optimisation, it's a job finishing after selling. And i think asus is already working on a new version of the board for Cascade lake X... I buy a X299 R6E to have the best for my job not to become beta tester, don't want to have to open the computer every 3 days before working on it! This is not my job.
