@Ced_RT , welcome to the Community.

Normally, once you update the BIOS/UEFI in the HP motherboard it is not possible to revert to the previous version.  I suggest that you assure that the BIOS is 1) set to ACHI/RAID and 2) you may have to disable Secure Boot.  Give this a try to see what happens.

What is the brand of the SSD and model and how did you do the clone of the HDD?

Hi!

thanks for your replay...

1) i haven't possibility su set ACHI/RAID

2) just try without secure boot... nothing change...

the bios version is really strang: 

on the hp official website, the latest official released version does not match with the version installed on my motherboar.

I think HP released my version (F.50) and then removed it because it didn't work properly. but now i can't use my pc as it should because my bios doesn't work properly .. and i can't even downgrade! absurd.

Thank you for the additional information, @Ced_RT!

I suggest that you contact the SSD manufacturer's Tech Support to see if they can help you.  They are the experts on their products.

 Finished a fresh install on a brand new SSD. Everything was running fine until the HP firmware update was installed via windows update (f.50).

Attempted to recover BIOS using usb for each ROM version (and older versios of 821D),  but each fail stating the BIOS files cannot be found or are corrupt.

Original platter drive still boots.

SSD is a Samsung EVO 860.
