bios does'nt recognize ssd

[Soroushqi]

hello there.

recently I bought a RAM and a SSD, ram works properly but i have some problems with the SSD.

SSD is 500 GB MvMe m.2 Samsung 980.

I installed it beside the HDD and just wanted to boot windows from it so it would be faster,

I transferred everything from Drive C to it, using Samsung migration app, it was a success and everything were there unharmed,

now here's the problem. first of all when the legacy support is disabled bios doesn't recognize SSD  at all, when i enable it, SSD appears in the legacy section but still not it the UFEI, and there's no way I can choose it to boot from it.

windows on the other hand along with Samsung magician do recognize the SSD. and I've tried so many things until now and I'm getting desperate, hope u can help me out.

tnq.

Hi:

Below is the link to the service manual for your notebook.

Maintenance and Service Guide HP Pavilion Notebook PC

Chapter 1, pages 4 & 5 have the supported drive types.

According to chapter 1, the M.2 slot only supports SATA M.2 SSD's.

However, it also indicates the slot supports Optane memory, which is NVMe.

I have read a few posts from other forum members regarding the 15-bc400 model series and they all seem to have problems with getting a NVMe drive to work.

This is what I suggest you try.

Make a bootable USB recovery drive with the HP cloud recovery tool, or use the media creation tool to make a plain W10 installation flash drive.

Here are the links for for both...

HP Consumer PCs - Using the HP Cloud Recovery Tool (Windows 10, 7) | HP® Customer Support

Download Windows 10 (microsoft.com)

Temporarily disconnect the 2.5" drive.

First try installing in EFI mode by booting the USB media from the EFI boot source.

See if W10 sees the drive and installs.

Then see if the PC boots and works fine from the SSD.

If it does, you will most likely need to completely format the 2.5" drive to remove any boot structure from it, or the PC will always want to boot from the 2.5" drive.

If it does not find the drive, then enable legacy mode, and see if you can install W10 on the SSD and if the PC works and boots up fine.

If so, then you will have to do the same thing with the 2.5" drive.
