BitLocker
When updating the BIOS on a computer with BitLocker enabled, consider the following precautions.
CAUTION:If BitLocker is not suspended
before updating the BIOS, the BitLocker key will not be recognized the next time
that you reboot the computer. You are prompted to enter the recovery key to
progress, and the computer displays a prompt for the recovery key on each reboot. If
the recovery key is not known, this can result in data loss or an operating system
reinstall. For more information, see Knowledge Article: updating the BIOS on Dell computers with BitLocker
enabled.
The installation of the following components triggers BitLocker:
- Hard disk drive or solid state drive
- System board
