What happens if you update BIOS with BitLocker enabled?

Caution: If BitLocker is not suspended, the next time you reboot the system it will not recognize the BitLocker key. You will then be prompted to enter the recovery key to progress, and the system will ask for this on each reboot.

Thanks you for your answer but it's "HP Connect " create the script powershell for remediation to update the bios why HP don't use suspend in the script

I doubt that  26 users clicked the "Turn on BitLocker" for the "C" drive and the other 4 did not.

It is likely the previous bios update together with a windows update triggered the problem.  

This has been a problem since last year and not  just affecting HP system.

the user don't have access to suspend bitlocker , they are only user not admin for the workstation/laptop. it's not possible for them to modify these.
