Suspend bitlocker before updating bios
Before updating BIOS or doing changes to the BIOS on a computer that has Bit Locker enabled, suspend Bit Locker encryption before you update the BIOS.If Bit Locker was not suspended, the computer will not accept your Bit Locker key the next time your computer boots and the only way you can start your computer is with a recovery key.
Another approach suggested online is to go to Encryption, which also seem to be non-existent.
Bit Locker has been around for several years and can be used with Windows Vista, Windows 7 and Windows 8/8.1 operating systems.
However, the focus of this article is on securing Windows 10 with Bit Locker.
Bit Locker Drive Encryption is built into the Windows 10 operating system and uses Advanced Encryption Standard (AES) with configurable key lengths of either 128-bit (default) or 256-bit (configurable using Group Policy).
The idea behind the Bit Locker Drive Encryption is that once you secure your drive, only you, or someone who has your password and recovery key, will be able to get to your data.
