NVMe SSD Not Showing in BIOS Boot Priority

[Serggge]

I have a problem with my HP Pavilion Power - 15-cb012. I have a 128GB WD Green NVMe SSD installed on the PC, but it does not show up in the BIOS, and it boots from the original HDD by default. I can access the NVMe disk (which already has Windows installed) by pressing F9 and selecting it as the boot device, but when entering the BIOS by pressing F10, it does not appear as a boot option.

I have physically disconnected the original hard drive, and it boots correctly from my NVMe disk, but when I reconnect the HDD, the priority is always set to the HDD, and I cannot set the NVMe as the default boot device

Any help, please?

@Serggge,

If you want to keep the HDD for data storage, you need to wipe the hard drive clean. Run Windows from the SSD by manually booting from it via F9 and use command prompt to do the job. 

Open command prompt as administrator and run the following command lines. Hit the Enter key after each line.

diskpart

list disk            [Find which disk is the HDD, most likely disk 0]

select disk 0  [If the HDD is disk 1, type disk 1]

clean

exit

I don't know how many partitions you want created on the hard disk. Open Disk Management and reformat and partition the hard drive the way you want from there.

If you want to keep the HDD as a boot drive and want to boot from the SSD automatically, there may be a way to do so.

Hello, Thank you. 

But in this way, all the data would be erased, right? . Is there a way to avoid having to wipe the HDD?

Thank u!

If you want to keep the HDD the way it is and automatically boot from the SSD, see if your BIOS allows you to do so.

Go into F10 BIOS Setup -> System Configuration ->UEFI Boot Order. Click OS Boot Manger, and if you see the HDD and SSD, as shown in this screenshot, use F5 or F6 key to move up the SSD to the top and save and exit to restart. Your system now should always boot from the SSD.

If you see only the HDD, you need to delete the EFI partition on the hard drive that contains the Windows boot manager. If you do this, you can view the content of the HDD from Windows on the SSD but no longer can boot from the HDD.

I did this....

And now mi HP doesnt start...

Appears

WINDOWS BOOT MANAGER

File \BCD
Status : 0xc0000034
Info: the configuration data file is missing some required information.



No way to start pc , I just delete partition EFI from HDD, ...

Looking at the error you posted, most likely, the entire EFI partition was not deleted, and the system is still trying to boot from the HDD prematurely, resulting in the error. 

How did you try to delete the efi partition?

[Serggge]

I did it with Diskpart, as indicated, and in Disk Management, I saw how the EFI partition was deleted, but I don't know why the EFI of the M2 also got damaged.

I used these instructions to repair the EFI partition of the SSD.
