The BIOS update should have been done from the BIOS Flash Utility within the BIOS and not via the ASUS Windows BIOS Flash program.

Re-flash the BIOS by following the steps in the first post found via the link below.

To enter BIOS ---- Reboot PC and then press F2 before the logo screen comes up, keep pressing / tapping F2 until you get to the BIOS.
If the laptop goes to Windows Login, re-boot and do it again, you have to be fast when pressing F2 to enter the BIOS.

Let us know how it goes.

Not working. Bios will not install bios 303 again. Because 303 are not newest bios so need to change bios version to 304 and change *version date.

Hmmm ! I know this works, I tested it before I posted the instructions here on how to flash an older BIOS.

What version of Windows 10 ? 32 bit or 64bit ?

Do you have all the latest drivers installed including the ATK drivers ?

Visit the link below and download the latest ATK drivers (You need to uninstall the old version and then install the new one and reboot the laptop.)


and also the IO / Serial Drivers for Skylake chipset.

http://ivanrf.com/en/latest-asus-drivers-for-windows-10/

After that try to install the Winflash software on the laptop.

If you get it to install, follow the instructions above to flash the BIOS back to 216 version.

Below is details of all the drivers I have installed on my G752VL -- the hardware is the same except for the Graphics card.

What is the Windows stop code that you are getting ?

I wonder if this will work .....

Is the BIOS set to RAID for the BOOT device ? (see picture below)

If it is, set it to AHCI mode and see if the M.2 drive will work / boot Windows.

Try these settings in the BIOS

Secure Boot = Disabled

Then change the CSM settings as shown in the 2nd picture below.

Change the BOOT mode back to RAID.

Save settings.

See if the M.2 NVMe drive will boot.

I'm sure it will work with SATA Mode switched to AHCI. If you get a blue Screen, wait for the part where it goes to try to repair your system and boot into SAFE Mode.
Restart your laptop. Should be okay now.

If you want to put it back to RAID mode, install NVME drivers from Samsung and iRST drivers from intel. Reboot your laptop into SAFE Mode by going to System Configuration and checking SAFE Boot under BOOT tab. Apply and exit then restart laptop. Before ROG logo appears, spam escape and go to SETUP bios. Change SATA mode to RAID, save and exit.
Your laptop should be able to boot into safe mode. Open System Configuration and uncheck SAFE boot. Restart laptop. Your laptop should now boot normally in RAID mode.

You can switch back and forth if you like, but booting into safe mode first everytime.

One problem with this, he is not able to get to boot in safe mode, the system will not boot the OS that's on the M.2 NVMe drive to change to safe mode.

If the error when trying to boot from the m.2 NVMe drive is the same as the picture below, when the computer reboots, it just goes into the loop with the same thing.

I had exactly the same problem. I have a G752VT with 950pro 512GB, BIOS 214, sata mode=AHCI. When updating the BIOS to 303, same blue screen unable to find boot device.

I went into BIOS setup and found sata mode changed to RAID. I pressed F9 for optimized defaults, changed RAID to AHCI, saved and exited. Still the same blue screen, unable to find boot device. I let laptop restart by itself, and the next blue screen is repair options. Just hit F8 for SAFE mode options, then F4 or 4 for minimal boot option. Windows should now boot in safe mode. Restarting should now boot Windows 10 normally. BTW, I don't have the Curator Update. Just the plain old version 1607 (OS build 14393.1198) Windows10 home.

Thanks for that Julskey.

I did a test here to see what would happen with Windows 10 Pro 1703 Build 15063.447.

Just let the laptop / PC do it's thing, don't turn off the laptop / PC.

Below are screenshots of each stage in order, when you see the Automatic Repair screen, select Advanced Options, after that the options picked / clicked on have a white box round them.

When you get to the last screen with options 1 - 9, press 4 for safe mode as mentioned above in Julskey's post.

Logon on, computer will start it 'safe mode', reboot and all should be good to go.
