Description and Symptoms

Symptom 1: “The drive where Windows is installed is locked” error screen on startup
The screen below is displayed when you attempt to start your PC. Unlike most errors, this error screen isn’t identified by an error code like the “Your PC needs to be repaired” error:
Causes of this Error
This error has been known to occur as a result of one of the following causes:
Cause 1: Bitlocker boot agent disabled
The root cause of this issue is due to the usage of Windows Bitlocker encryption. Bitlocker is a whole-disk encryption used to secure user data, but requires that the Bitlocker boot agent be installed. At boot time, this boot agent is used to unlock the Windows drive before attempting to load Windows 7, Windows 8, or Windows 10. If this agent is disabled or overwritten, either on purpose, by accident, or due to 3rd party interference such as 3rd party bootloaders or malware infecting the boot process, this error message can appear.
Cause 2: The TPM has been cleared or reset
BitLocker can optionally use a hardware encryption chip found on most modern PCs and laptops known as the TPM (Trusted Platform Module) to manage the secret keys used for the encryption of data. If this TPM is cleared or lost, either due to the user clearing the TPM manually in the BIOS/firmware setup or due to a TPM firmware upgrade as part of the system firmware/BIOS upgrade process, the keys the TPM contains may be cleared and the system will fail to boot.
Cause 3: BCD file is damaged
The BCD(Boot Configuration Data) file that contains boot configuration parameters for Windows system, is a very important part of booting process. If that file becomes damaged, then the boot process is halted.
