My new laptop has Windows 10 installed with the Intel

FC31 is on a SATA ssd.
BIOS allows me to choose AHCI or RST. I must use AHCI to boot the FC31
drive, and RST to boot the Windows drive. Neither will boot with the
other. Sigh.
1. Is there a way to get the FC31 drive to boot with RST ?
2. Any way to have the Windows drive boot with AHCI ?

I have Intel RST "fake RAID" on my Lenovo ThinkPad P72. As delivered,
Windows 10 Pro was installed on two 2TB NVMe SSDs in a RAID1 mirror
configuration. While I could have also installed a standard notebook
SATA SSD, I postponed that idea (see below) and broke the RAID1 mirror
instead. The BIOS Storage setting gave me two options: RST or AHCI. The
BIOS is wrong. It should say RST or NVMe. SATA or AHCI are not options.
And boy are the two raw NVMe drives F-A-S-T !!!!
I went through all the hand wringing and fear of screwing up something I
didn't completely understand at the time. I backed up everything I could
think of from Windows 10, and a went to the trouble of getting a Lenovo
ThinkPad Windows restoration thumb drive.
Happily, once I broke the RAID1 mirror, I was able to boot to a Fedora
live ISO on a thumb drive. It could see both /dev/nvme0 and /dev/nvme1
SSDs. The #0 device still contained one half of the mirrored Windows 10
installation. fdisk shows the following detail:
# fdisk -l /dev/nvme0n1

This frees /dev/nvme1n1 for a normal installation from a live CD image.
It will set up GRUB2 for a Windows + Fedora dual boot. When installed,
your second NVMe drive should be partitioned something like this:
# fdisk -l /dev/nvme1n1

As I indicated above, I later installed a 4TB SATA internal drive in an
expansion space inside the P72. I had to buy a wiring adapter to connect
the SATA drive to the P72's internal chassis wiring. That wiring doesn't
come instsalled from the factory. I got the kit from EggHead.
Hope this helps.

Very interesting. Are you now able to boot into Windows on nvme0 from grub ?
