HP G40 G5 nvme not being recognised

[Hayche1992]

I have the HP G40 G5 and I upgraded the stock nvme m.2 to a Samsung 980 NVME.

But I can't see the drive in windows 11 or windows 10 installation via usb.

The drive also doesn't show in bios. I have given up I'm not sure what the problem is?

Thanks for getting in touch with the HP Support Community. We’re happy to assist you with your concern.

If your HP EliteBook 840 G5 is not detecting the Samsung 980 NVMe SSD, neither in the BIOS nor during the Windows installation, you can follow these troubleshooting steps:

1. Check Physical Installation:

   • Ensure that the SSD is properly seated into the M.2 slot. Remove and reinsert the SSD to confirm it’s securely connected.

2. BIOS Settings:

   • Access BIOS by pressing the F10 key when the system is booting.
   • Look for an option related to "Storage" or "Boot Order" and ensure NVMe support is enabled, if such an option is available.
   • Update the BIOS to the latest version available on the HP support website. Outdated BIOS versions might not correctly support newer SSDs.

3. Enable UEFI Boot:

   • Ensure the system is set to UEFI mode rather than Legacy. Go to BIOS settings and check for "Boot" options.
   • Secure Boot should be either enabled or temporarily disabled to check if there’s a difference in SSD detection.

4. Compatibility Check:

   • Confirm that the Samsung 980 NVMe SSD is compatible with your EliteBook 840 G5. The laptop may have specific requirements for supported SSDs.

5. Check with a Different System:

   • If possible, test the SSD on another system to verify whether the SSD itself is functioning properly.

6. Reset BIOS Settings:

   • Sometimes resetting the BIOS to its default settings might resolve detection issues. Look for the option to "Restore Defaults" or "Load Setup Defaults" in the BIOS.

7. Install Necessary Drivers:

   • For the Windows installation USB, ensure you have the latest storage drivers available. You can include these drivers on the USB so Windows can access them during installation.

Do keep us posted on whether these steps resolve the issue. We’ll be happy to assist you with the next steps.
