@a4cheong:
Thanks for the screenshots.
Please re-attach them after having done the following:
1. Disk Management: Right-click onto the Win10 Start button and choose the option "Disk Management".
2. BOOT order: Enter the "BOOT" section of the BIOS, set the "Windows BOOT Manager" into the first position of the boot order, insert any USB Flash drive and hit the F12 button.
This is how the pictures should look (but all in English language):

@all:
This thread has been designed for users, who want to get full NVMe support for their old PC with an AMI UEFI BIOS by trying to do the related procedure themselves. Since I didn't spend the time writing and updating detailed guides like the one within the start post of this thread with the intention to do in the end everything myself, I generally do not modify anything upon request.
Users, who just want an already NVMe modded BIOS for their specific mainboard/system and are not able or willing to follow my guide, can search for it within >this< Sub-Forum or send a private request to our BIOS Guru Lost_N_BIOS.

@Lost_N_BIOS:
It is no problem to insert the NVMe and the "SAMSUNG_M2_DXE" module simultaneously.

@Svan:
You obviously misunderstood my guide (= start post of this thread). The NVMe EFI module should not be inserted into the CSMCORE module, but into the "DXE Driver Volume", where the BIOS module named CSMCORE usually is located and listed (Note: Some BIOSes have more than 1 "DXE Driver Volume").

In the very rare case, that a module named "CSMCORE" shouldn't be listed at all by the MMTool or UEFITool, the NVMe module has to be inserted into the first (=upmost) Volume, which contains "DXE Drivers".

EDIT: To avoid any future misunderstandings regarding the target location for the insertion of the NVMe module, I have just now added some additional information into this part of my guide.

Instead of modifying by repeating the steps and risking turning my laptop into a brick, I prefer to ask someone to do this modding for me, Someone who KNOWS WHAT HE DOES and not just repeats as the instruction says - having no idea what is going on.

1. Not the BIOS modding procedure itself, but only the flashing of a wrongly modded BIOS is risky (may brick your mainboard/system). It is very easy to minimize such risks by posting the self-modded and the original BIOS into this thread and to ask for an analysis and a verification, that the BIOS has been correctly modded.
2. Only by trying to do the BIOS modification yourself you will get knowledge about the structure of a BIOS and about what happens or may orrur while trying to get any natively not present BIOS module inserted.
3. If you let the BIOS modding been done by someone else, you will be dependent on such expert in the future. Every time the motherboard manufacturer releases an updated BIOS version that you want to flash, you'll need to bother an expert again and ask, whether he will do it for you.

@Outbreak:
Welcome to the Win-RAID Forum!
Please enter the BIOS, open the "BOOT" section and look for a Disk Drive named "PATA" or "PATA_SS".
If it is listed, your BIOS modding and flashing work was ok and you should be able to get Win10 properly installed onto your NVMe SSD in UEFI mode.
If no such Disk Drive is listed within the BIOS, your BIOS modding work was not correct or the BIOS hasn't been successfully flashed into the BIOS chip of your mainboard. In this case I recommend to attach the original and your modded BIOS as *.ZIP or *.RAR archive. Then we will analyse it and tell you our result.

@Outbreak:
The file named P8Z77-V-LX-ASUS-2501_MOD_4.CAP has been correctly modified and should support NVMe after having been successfully flashed.
So I suspect, that the flashing procedure didn't work as it should.
Regarding the flashing procedure please have a look into the start post of >this< thread (Chapter B of the ASUS Guide).
If you should have any further questions regarding the BIOS flashing, please post them into the related thread.
Once you succeeded, please give us your feedback within this thread.
Good luck!

@Outbreak:
1. Is your NVMe properly connected via adapter to your mainboard?
2. What lets you believe, that the flashing procedure was successful?

@Outbreak:
Did you follow exactly this guide?

No, I couldn't find a afuwinx64.exe that worked.
