BIOS was Failed and was recovered from USB. And then SM961 SSD NVME was not recognised on the BIOS.

Dear EveryOne.

I was using SM961 SSD NVME on Z820. SM961 SSD was system drive and worked well.

BIOS was Failed on Z820 and was recovered(63, 3.94) from USB. I downloaded it from HP suppertor.

After that, I can not boot from SM961 SSD and can not see any information SSD in Bios.

I ran computer by using USB and could see SSD. SSD is normal, but can not set it as boot drive.

What do I have to do for use of SM961 SSD as a boot drive?

Please help me.

Thank you.
