What is the storage settings for the onboard controller? AHCI? 

 

The problem you describe doesn't match exactly what I have seen most cases but it was my initial thought after reading about a failed boot after a BIOS update, as it usually resets defaults.

Hi,

 

My new PC failed to boot after bios update. 

The total use time may be less than 5 day! 

 

After installing Windows 10, I tried to update the BIOS. And then Windows failed to boot. 

I tried to re-install the OS but it didn't detect the drive. 

The drive is detected in UEFI, and also Windows 10 shows loading but then failed to boot. 

 

Here is the hardware list:

Asus Z370 Prime-A

M.2 Samsung 960 EVO - 1TB

Intel i7-8700K

G.Skill Trident RGB - 64GB (16 x 4)

Nvidia Quadro P4000

 

OS: Windows 10 Pro 64-bit

 

 

The BIOS update was done natively in the UEFI via internet to version 606 (latest release). 

 

After OS failed to boot, my troubleshooting was to get BIOS version 605, then tried 606 again, then original first release 408. All of these was via USB after downloading them from ASUS website. 

Lastly, I retried version 606 updated via internet.

In all of these trials, OS (Windows 10) failed to boot. 

I tried to physically remove the M.2 and re-installed it again.

 

All with no luck. 

 

I appreciate it if anyone can help me to fix this issue. 

I haven't got that much of things installed on it. If I couldn't solve it, I'll return it to the retailer.

 

Thanks for your help :)

I own the same motherboard and CPU with the latest bios, no problems at all.

Are you running at stock or OC'd in the bios?

Stock. 

All default settings. I haven't changed anything.

Sounds like a corrupted Bios.

Try this to reset it.

(From the Prime z370 manual)

 

ASUS CrashFree BIOS 3
The ASUS CrashFree BIOS 3 utility is an auto recovery tool that allows you to restore the
BIOS file when it fails or gets corrupted during the updating process. You can restore a
corrupted BIOS file using the motherboard support DVD or a USB flash drive that contains
the BIOS file.
The BIOS file in the motherboard support DVD may be older than the BIOS file published
on the ASUS official website. If you want to use the newer BIOS file, download the file at
https://www.asus.com/support/ and save it to a USB flash drive.
Recovering the BIOS
To recover the BIOS:
1.
Turn on the system.
2.
Insert the motherboard support DVD to the optical drive, or the USB flash drive
containing the BIOS file to the USB port.
3.
The utility automatically checks the devices for the BIOS file. When found, the utility
reads the BIOS file and enters ASUS EZ Flash 3 automatically.
4.
The system requires you to enter BIOS Setup to recover the BIOS setting. To ensure
system compatibility and stability, we recommend that you press <F5> to load default
BIOS values.

Thanks for this, but I have tried this with multiple versions 606, 605, and 408 (original release). All failed to fix it. 

The only step I've not done in that procedure is the last one

(press <F5> to load default BIOS values.)

 

But I don't think it will make that big of a difference.

OK, have you tried a Windows repair install from a USB?

I had similar issues with my old ASUS X99 system. I thought it was the bios at first, turned out Win 10 was corrupted.

Took me 3 re-installs to get it working properly.

When Win 10 failed to boot, it went to restore/fix page (I don't know its official name :D), the auto fix tool didn't detect any problem.

And when I tried to re-install Windows via USB, it didn't detect my M.2 drive. It just said there's nothing.

What is the storage settings for the onboard controller? AHCI? 

 

The problem you describe doesn't match exactly what I have seen most cases but it was my initial thought after reading about a failed boot after a BIOS update, as it usually resets defaults.

It seems AHCI is the default setting and somehow was changed to IRST (RAID). 

Should I change it to AHCI? 

 

I'm using M.2 Samsung 960 Evo.

I switched back to AHCI and it's now working completely OK.

No re-install... and nothing.

 

@Storytellar Thanks so much. ^_^
