I updated Windows 11 and, among other things, updated the bios. Since then I haven't seen one of the discs. What to do? Is there a way to fix it?

Some "discs" are just partitions on the main drive that are supposed to be hidden. 

HP systems typically have a Bios backup partition, a system recovery partition and a UEFI partition for diagnostics.  Typically they are hidden but on occasion they are visible which is an error.  Possibly upgrading to win11 caused these partitions to be hidden like they are supposed to be.

Alternately, the BIOS upgrade may have changed an important setting and a real disk drive is not longer visible.   I do not know what type of HP system you have but if Intel and you have Optane memory (a type of disk drive) then the BIOS needs to have RST enabled instead of AHCI.

How did you do the upgrade to win11?  Did your do a clean install that removed all your partitions or did you just run "setup" or "update" from inside windows 7,8 or 10 ?
