M.2 NVME on HP Elitedesk 800 G3 DM 35W

[tthakur]

I am planning to upgrade  HP Elitedesk 800 G3 with M.2 NVME however 
however, I am unable to see that in the system 
When I got to bios UEFI drivers I was able to see both the drive
1) Old SSD

2) M.2 NVME

I there any setting that I am missing here 
the secure boot option is "legacy support disabled and secure boot disabled"

@Paul_Tikkanen if you can help

I don't quite understand the problem.

You can install Windows on the NVMe SSD without seeing the drive in the operating system.

If you want to see the NVMe SSD in Windows, you have to initialize the drive.

on current setting
I have 1 drive with SATA where I have installed the PROXMOX, I wanted to add another ssd to use it for ceph filesystem. I can see this in  but not after starting the machine ( not even the HP BIOS)

Unfortunately, I won't be able to help you.

I have the same model 800 G3 DM with an i5-6500T processor.

I removed the 2.5" SSD because I have no need for two drives.

I installed a Samsung 980 1 TB NVMe SSD and installed W11 (using a W11 hardware check bypass hack with Rufus) on the drive.

It's been working fine for a year now.

I didn't even bother to look if the NVMe drive showed up in the BIOS or not after I installed the drive.

I booted from the W11 installation media from the F9 boot options menu, it found the NVMe drive and installed.

Thanks for update , ill try the same lets see if this works

You're very welcome.

I'm pretty confident all you need to do is boot from your Windows installation media and it will find the NVMe SSD.
