This problem is back.
As mentioned in this thread attempting to install via Windows 10 via a USB drive does not see the NVMe M.2 sticks (I have two 1 TB sticks that came with my P70 from Lenovo).
I did an install back around on Nov. 29, 2016 and it worked back then using the USB drive + drivers I left on the stick. Since then I've kept my machine current so I'm not sure what's changed (BIOS did get updated0.
My P70 is a model 20ERCTO1WW.
BIOS is N1DET83W 2.12
Can we get updated drivers ASAP Lenovo?

What Windows 10 image are you trying to install? If not the Lenovo preload image, then you must slipstream the Intel RST driver to recognize the RAID 0/1 drive into the install image. The thread that you referenced recommended that the OP use the Lenovo image to be downloaded from the DDR site.

Thanks for the reply. I'm using a custom image built via an MSDN ISO of Windows 10 Pro AE (1607). I've added the RST drivers to the USB stick in folder that I load during the install.
To be clear, I used this EXACT USB stick just over a month ago to build the current main image I'm using on the P70 that is booting from the NVMe RAID 0 set. IOW, it worked before.
At the end of the thread I reference, Lenovo acknowledges they introduced a bug and provided an updated driver. My guess is they've added the same bug back or something new.
Bottom line is my USB install worked "just fine". I'm trying to add an additional install which I've done my times before including my W510s, W520s, and W530s. My W530 for example right now quad boots Win7, Win8.1, and two Win10 images.

I'm understanding that you want to install two bootable copies of Windows 10 on the same P70 using the same RAID 0 array, correct? Have you created multiple partions on the existing RAID 0 to support the installation? If so, then I do not believe that the P70 can support multiple simultaneous RAID arrays. Even if you have 4 HDD/SDDs defined, only two of the drives can be used for the RAID 0/1 array. What you quote from the thread you referenced was the need for an updated RST driver set from Intel, not a bug in the P70. There is no separate RAID controller in the P70 (fake RAID) so the CPU is used through the chipset to support the functions.

Edit: fixed typos and added note.
Note: I do appreciate the conversation and hope I'm not coming off as snide. Just trying to provide details.
System came from Lenovo as follows:
P70 64GB ECC with two "OEM"(1) NVMe 1TB sticks with two Toshiba 500GB HDD. All four drives came as individuals with one of the NVMe drives as the boot drive (so C:, D:, E:, and F: drives) running Windows 10 Pro.
P70 64GB ECC with two "OEM"(1) NVMe 1TB sticks with two Samsung 850 EVO 2TB SSDs I added myself.
I used True Image to backup the OEM install of Windows 10 Pro.
I reconfigured the system with TWO RAID arrays via the BIOS.
One is RAID 1 using the two Samsung 2TB EVOs.
The other is RAID 0 using the two NVMe sticks.
I restored Window 10 to the RAID 1 config so when booted I have a 2TB (RAID1) C: drive and a 2 TB (RAID 0) D: drive.
I then proceed to install Windows 10 into a Native Boot VHDX as well as Windows Server 2016 into a Native Boot VHDX.
Both VHDX images are stored on the RAID 0 drive. I was able to install both by manually "loading" the RST driver during install.
This week I tried to add a 3rd VHDX. Repeating the steps I did above, I cannot see the RAID 0 "drive". However, I can install the VHDX on the RAID1 drive and then once installed, install the RST drives and "see" the RAID 0 drive.
So right now when I boot up I can pick one of four configs:
Windows 10 via a VHDX booting off the RAID 0 array.
Windows 10 booting off the RAID 1 array (OEM install).
Windows Server 2016 via a VHDX booting off the RAID 0 array.
Windows 10 via a VHDX booting off the RAID 1 array.
Is this an advanced config yes. Do I *think* I know what I'm doing. Generally yes.
IMHO this is a problem/bug in the Intel RST driver and/or ThinkPad BIOS.
(1) I can't seem to prove what kind of sticks are installed. They came from Lenovo.

Very interesting. I didn't know that the P70 could support multiple RAID arrays concurrently. There must have been an enhancement to one of the recent BIOS. The OEM 1TB M.2 sticks are Samsung PM961.
