The Asus support center is trying to blame my installation media, a USB stick that I've used to install W10 before...
The CSR COMPLETELY missed the M.2_2 slot not working refuses to anything more than escalating the problem to the next tier.
Not happy with Asus ATM.
Tell me about it... But escalating might have helped in my case. They did bring me to the point of dispair though before escalating, but moved on after I hammered their heads. So, maybe there is still hope. Just continue to hammer in that they missed to check the m2.
On another hand, to eliminate any argument on their side and try one final time, I am not sure if you tried the "longer" version, but would you want to attempt the "advanced" board clearing?
I don't know if you are interested to try and update the BIOS again, but I think you've mentioned that it's a Maximus board. So perhaps you would want to use BIOS reflash method with the BIOS button on the back of the board (no cpu,no ram, no ssd, just PSU's 24pin and 8pin connected to the board and the correct bios with the correct name, placed on USB formatted in fat32 in the designated bios reflash USB slot on the back). I used this week it on a Maximus VIII that was giving me an Error00 with a perfectly good cpu, and it solved some things, followed by a "deeper" clear cmos[IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]
After a successful flash, check the bios. Then remove the PSU cable, then remove CMOS battery, then short the CMOS battery base and side for over 10sec (redundant if you use the next method, but I did that to be 200% sure). Then short the power pins - the 3rd&4th upper pins, from left to right, on the Front Panel Header on the board, for 2min - just take a screw driver and place the metal part on those two pins and leave it for 2min. Or keep the power button on the board pressed for 2min, though people suggest 30sec is enough, but I'd rather be sure and keep it for 2min. Then remove the screwdriver/unoress power button and leave the board in the box overnight, still without the CMOS battery.
Next day download the latest Media Creation Tool, from Microsoft, on your USB. Then place the CMOS battey back, and try a fresh install again, with m2 drive, but no other ssd or hdd. Before that check the BIOS if it sees your M2.
I, of course, don't know, maybe you know all of that, but it's worth to try nonetheless if you didn't do the whole "deep cmos clearing" 😉 thing.
