Updating BIOS on systems with BitLocker enabled

CAUTION: If BitLocker is not suspended before updating the BIOS, 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. If the recovery key is not known, this can result in data loss or an unnecessary operating system

reinstall. For more information about this subject, see Knowledge Article: Updating the BIOS on Dell Systems With

BitLocker Enabled
