The recovery partition is a special partition on system hard drive and is used to recover your system when the computer crashes. There are two types of recovery partitions. One is Windows recovery partition created by installing Windows on GPT disk. Windows recovery partition only takes up several hundred MB disk space, as it only contains the operating system.

The other one is the suppliers' recovery partition created by computer manufacturers like Dell, HP, Lenovo, and Asus. This sort of recovery partition also allows users to restore the computer to factory default settings, including OS, drivers, and some build-in applications. Hence, it takes more space than Windows recovery partition and is usually marked as OEM Partition.

About “The drive where Windows is installed is locked”

The following information on this error has been compiled by NeoSmart Technologies, based on the information gathered and reported by our global network of engineers, developers, and technicians or partner organizations.

Description and Symptoms

Asus Windows 8 Recovery Disk Iso

The error messages, alerts, warnings, and symptoms below are tied to this error.

Asus

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.
