What Is The System Reserved Partition And Why Is It Created?
The System Reserved partition is a small partition created by Windows during the installation process. It serves as a boot partition that contains the Boot Manager, Boot Configuration Data (BCD), and other system files necessary for booting Windows. The System Reserved partition is usually around 100MB in size and is assigned a unique GUID.
The main purpose of the System Reserved partition is to provide a separate area on the disk for system files that are critical to the boot process. This allows Windows to boot even if the main operating system partition becomes corrupted or is unavailable. The System Reserved partition is a hidden partition, meaning it is not assigned a drive letter by default, and is not visible in File Explorer.
Why Doesn’t The System Reserved Partition Have A Drive Letter?
The System Reserved partition does not have a drive letter by default because it is not intended for user access. Microsoft wants to prevent users from accidentally modifying or deleting critical system files that are stored on this partition. By not assigning a drive letter, the partition is protected from user-level access, reducing the risk of accidental modification or deletion of system files.
This approach also helps to prevent malware from infecting the system files on the System Reserved partition. Malware often targets system files to gain control over the system, and by not having a drive letter, the System Reserved partition is less accessible to malicious software.
