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 re-install. For more information on this subject, see Knowledge Article:
