BitLocker hijacks the boot procedure and searches for changes made to old boot files. While this is beneficial, it also can cause problems after; replacing motherboard or TPM, installing a new OS, updating BIOS or when making new hard disk partitions. Other scenarios that cause conflict with BitLocker include moving a HDD to a computer with TPM and also when 3rd party updates are installed e.g. firmware updates. Here is how to disable BitLocker drive encryption in BIOS when you face such problems;

Method 1: Turn off BitLocker Password from BIOS

This technique covers how to turn off BitLocker from BIOS screen without logging in to Windows first.

1. Power off and restart the computer. As soon as the manufacturer logo appears, press “F1”,”F2”, “F4“ or ”Delete” buttons or the key needed to open BIOS feature. Check for a message on the boot screen if you don’t know the key or look for the key in the computer’s manual.
