Yes, typo .. at 4 am this morning. Couldn't sleep so I did a Boeing Dreamliner X-Plane 10 flight from RJBB Kansai to YBBN Brisbane to make me sleepy
This is likely just a typo, but a drive is either AHCI (SATA) or NVMe.
If that doesn't work, Try rebooting the Mac and hold down the "Alt/Option" key and select the "More Options" option, as the drive is an internal partition, the Mac will save it as the default boot drive. (Requires a Mac EFI GPU)Thanks for providing the detailed instructions.
I created a 100MB partition on an internal HDD. Make it MS-DOS FAT, and then restore from the image file.

But can't see it in the Start up disk selection yet.

I don't know if you're using High Sierra, but the Bless command seems to be bugged in High Sierra and doesn't always work, that could be the reason why it doesn't appear in macOS but appears in Windows.Interestingly. If I boot to Windows, I can see that in the Bootcamp apps. But I didn't try it yet.

If it's smooth. Or I can pull out the HDD and let it boot back to Windows then I will be fine.
But if it stuck at a unbootable partition, and I can't fix it by simply pull out the HDD (but require to install a Mac EFI GPU), I don't have the time to do that now. So may be test it later when I have more free time.

If the option does not appear, run the ./scripts/bless_volume.sh script

SATA drives are always AHCI. PCIe drives can be AHCI or NVMe. (A PCIe AHCI drive has a PCIe connection (not a 6Gbps SATA cable), but speaks the older SATA protocol.)
If there are any dual-mode (one PCIe drive that can do AHCI or NMVe), please correct me.
Yes, It's normal.I am using the latest 10.13.4 17E202 indeed.
Also, A quick quick question to ask. That little partition auto formatted to HFS+ after restore from the image file. Is that normal? From memory, it's the very 1st boot loader that I've seen using HFS+.
You're good here - at the electrical level. (Let's ignore edge cases like mSATA for now.) SATA drives connect over the SATA protocol - even when using a PCIe physical connection. AHCI is for all practical purposes the same as SATA - although AHCI is a slightly higher protocol layered on SATA.I'm confused. I thought that PCIe and SATA were two different types of computer connections (interfaces)
Close - but not really a "controller" in the sense of a RAID controller or HBA. AHCI and NVMe are the "languages" that the disks understand.and AHCI and NVME are different types of controllers for SSD drives
Not just confused, but wrong.. and that both types (AHCI or NVME) can be installed on a cMP's SATA bus or in a PCIe slot. Again, confused

We can be optimistic that in either Gold Master High Sierra or OS X 10.14..x they will relent abd come to their senses.
The final version of Next Loader will have a easy to use graphical installer. I only need to do more testing and find some beta testers.I think that what we really need right now is an "easy point & click" tutorial ( with graphics ! ) a clear, explanation to allow ALL cMP owners to (1) Be able to see NVMe drives in Sierra. = DONE ( 2) The same in High Sierra. ( 3 ) Be able to BOOT from those NVMe drives .. .( 3) either through FUSION = DONE or rEFIND. but . .
Obviously, Apple knows how to do this for 4,1>5,1 cMPs otherwise there would not have been a firmware update to our older cMPS.

Thanks for the feedback, I don't know why Windows booted automatically, the boot loader doesn't have a timeout.Just tried to select the Next Loader partition in Windows 10.
Reboot. No GUI (My GPU is the PNY XLR8 1080Ti, should has UEFI GOP), black screen may be for 15-20 seconds. And then auto boot back to Windows. Not sure if the loader timeout and then auto boot to Windows. Or can't boot to Next Loader. Nothing on the screen, can't see.
holy sh*t the french guy did it! flashed modified boot ROM and now it boots native from an NVMe SSD!

Impressive but I think that desoldering the boot ROM flashing it then soldering it back onto the motherboard may be a step too far for most Mac Pro hobbyists.
Today I released an update of Next Loader including several changes in the way it is compiled, now the drivers are compiled directly from the EDK2 UDK2018 source code, this includes the NvmExpressDxe and UEFI GOP driver..
I just made and uploaded to the GitHub repository a super easy to use installer.How about a precise, step by step tutorial for those who are not expert Terminal users( such as myself ) ?
I don't really know, I know about some people who managed to boot without problems using NvmExpressDxe but other people (usually those using Apple branded NVMe blades) had to use the Apple's NVMe driver. Next Loader includes both drivers, in order to provide compatibility with as many NVMe blades as possible.I wonder how much more compatible the NvmeExpress driver is vs. Apple's NVME driver.
Porting these drivers to the Mac Pro 4,1 and 5,1 firmware should be doable, if they are compatible with the Kernel Apple uses for EFI on these Macs.
Someone should try and load them from a shell.
