5820 workstation with nvme flexbay: does 4tb crucial P3 work in flexbay?
I have a dell precision 5820 with a flexbay for the upper two drive housings and SATA for the two below. In the left upper bay I have a working 1tb boot nvme drive, which sits in the u.2 adapter. It is a Toshiba 1tb nvme. I want to replace it with a 4tb crucial P3 nvme.
Bios sees the 4tb as an nvme storage device. But it won't boot, and a usb stick windows recovery won't recognise it.
When I boot to a fedora Linux usb stick it can see the 4tb nvme in the flexbay and see it's contents.
I downloaded the nvme drivers from the crucial web site, but windows doesn't recognise them as compatible. When I load them anyway they don't allow the drive to show up.
Any thoughts? I have a pcie card for nvme, but I want to make use of that bay.

Previously I had updated the BIOS.
Now I went to the dell support page, ran a scan, and got it to update all my drivers. Rebooted and the NVME is detected and working in Secure boot. Problem solved.

Bios is latest Feb 2025.
My nvme is the Crucial 4tb m.2 PCIe Gen3 NVMe SSD CT4000P3SSD801.
In bios in pcie drives, my drive shows as CT4000P3SSD8 on mini-sas pcie ssd-0.
I tried disabling all SATA drives, as someone suggested this. It made no difference.
SATA is set olti AHCI.
Uefi secure boot is disabled.
Enable legacy open ion ROMs is on.
Enable attempt legacy boot is not on.
Vmd is set to auto.
I put the original, working, 1tb nvme, on my HP Z turbo pcie card which hosts an nvme. It isn't detected by the machine as being in a pcie slot (empty). The GPU is detected.

In legacy mode, with try legacy boot on, after a reboot, my 4tb nvme appears in bios as a boot option. It won't boot the drive, and goes on to windows usb stick which can now see the drive.
Startup repair won't work. But I will have a go at the usual tricks with fixmbr etc. This is an nvme from my hp z840 which I have my stuff on (safely backed up).
In this latest effort I think I turned off all the sata (hard to remember all the combinations). Not sure if that is a factor, or needing to turn on legacy and legacy boot attempt made the drive visible.
No idea if I need to keep these settings once windows boots from the usb.

I used command line from my windows repair disk to "fix" the boot on the 4tb windows nvme which I moved from my hp z840.
I rebooted, hit f12 to choose what to boot, and booted the uefi option for my drive. Windows started and said it was getting drivers ready. Another reboot and hitting f12 I have a uefinoption for the windows boot loader
Now I am back into my windows environment on the 5820 with my 4tb drive. I will have to update drivers for this machine. But so far it looks good.

I cloned the Crucial P3 4tb NVME I was using, in the u.2 adapter, onto a 4TB SATA hard drive which I placed in one of the lower, SATA, drive bays. It boots Windows 11 fine. There is nothing wrong with the OS image on my NVME drive. Another NVME works in that u.2 adapter (the 1tb nvme which came with the machine). It seems that the 4tb nvme drive isn't compatible with the 5820 or I need some kind of firmware.
