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:
