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, please see Knowledge Article: http://www.dell.com/support/article/us/en/19/SLN153694/updating-bios-on-
