Thanks Ethaniel,

these are actually clever tips; however, I decided to make my new nvme ssd a win 10 clean install (win 10 USB install stick had no trouble finding the new SSD). I can alway play games in Win 7 while slowly migrating work apps to win 10.

Regards - Bill

I did a clean win 10 install on the nvme SSD with no problems - thank you. I can slowly migrate my work apps to it while keeping my games on win 7; ultimately, I can move my steam account to win 10 and have it redownload the games I care about overnite.

Oddly, AS SSD bench game me 1200 / 800 MB sequential as a win 7 storage device, but win 10 (as system) gives me more like 800 / 600 MB. I checked system disk activity (0 - 1%) and ran the benchmark multiple times but never matched the win 7 storage drive #s.

I wish to know that after this modification, can my nvme ssd boot in MBR+LEGACY mode or i must use GPT+UEFI boot?

On my Z87 Gryphon i just can't do this.
After injecting NvmExpressDxe_4.ffs or NvmExpressDxe_Small.ffs and flash it (via Asus AI Suite - EZ Flash by replacing file just before flashing) i cant boot up.
"WARNING! BIOS Recover mode has been detected..." so I'm trying again by putting pendrive with file Z87GP.CAB (modded one) with same result, only non-modded Z87GP.CAB boot up pc.

Anyone can help with this?

@Fernando:
I used flashback option but an not flash modified bios by flashback. Only original one

If your mainboard suppports the USB Flashback feature, you have done something wrong (wrong BIOS name/USB port/USB Flash Drive?).

i mean this after flashing by Asus AI

and i can't flash custom, only original via flashback/recovery

yes it does

First i modded bios by addin NVMe, next save/verify and flash via AI Suite 3 (method with replace file before flashing)
But after reboot i got problem (look onedrive link)
So i try one more time this time by USB stick, rename file but won't work. Can flash only not modded file. Bios can't flash modded because of security reason, and flashback (see onedrive photo) also can't.
