It started with windows 8.0 and continues today with 8.1 and 10. PCI-E M key only booting became standard with UEFI Class 2.3.1 bios.
Intel started discussing this back in 2009 PCI-E is not backwards or forwards compatbile for secure boot and power and line code reasons. Fitting into the slot does not guarantee working even when there is sufficient power to go along with that aka 1000W power supply. Thats why Older models like Precision 490 and 690 with PCI-E 1.1 bus cannot use newer cards. PCI-E bus uses 128b/130b encoding and much faster speed for 2.1 and 3.0 and up. PCI-E bus uses 8b/10b encoding and slower bus speed for version 1 to 2.0
NVME BOOT UEFITOOL 64 BIT
All new systems past skylake chipset are WIN10 only 64 bit only end of story. Upon completion of the editing process, you can easily export the image. One reason is that they support 32 bit XP as well as MSDOS and MBR Legacy booting. UEFITool will permit you to extract data from an image, insert items within the structure of the image, and insert or remove unwanted pieces as needed. Machines like the 7 will never have class 2.3.1 UEFI secure boot bios. It is no problem to get a M.2 connected NVMe SSD working with any Intel Chipset system from 6-Series up without modifying the mainboard BIOSfile, if the NVM. The 7010 has CLASS 1 UEFI which does not allow GPT booting because its compatable with 32 bit XP with MBR.
NVME BOOT UEFITOOL UPDATE
Once the light becomes solid on, the update is completed. The light on the motherboard, next to the internal BIOS chip, will start to flash and get faster over the 3-4 minutes the process takes. Its likely that they also have PCI-E bus 2.1 or newer. Press the Flashback button on the rear I/O panel next to the white USB slot the drive should be placed in.
Thanks for letting everyone know Patrick very. The latest UEFITool insert doesn’t work). The PC just restart immediately after shutdown and go to login screen after hibernate. Models that came out after 2013 and have windows Genuine COA will be UEFI Class 2.3.1 complaint. After getting NVMe boot working, the hibernate and shutdown on my PC was not working properly anymore. With UEFITool0.28.0win32 I loaded the full and just the bios part and added the nvme module NvmExpressDxe5 after the last entry just as described in the guide. UEFI class and PCI-E 3.0 Bus are the issues.
