System Reserved partition on the wrong drive occurs when the system partition and the system reserved partition are not on the same disk. Why would the system reserved a partition on the wrong drive? In this article, we will explain this error in detail and give a solution to the problem. Before we start, let's understand what a system-reserved partition is.

What Is a System Reserved Partition

The reserved system partition stores boot files. A Microsoft system reserved partition is created when the Legacy BIOS and MBR partitioning scheme are used; an EFI system partition is formed when the UEFI BIOS and GPT partitioning scheme are used.

These two are reserved system partitions because they both have the boot files needed to load Windows. The absence of this partition prevents your computer from starting.

Summarizing, there are two parts:

  • Boot Manager and Boot Configuration Data
  • The startup files used for BitLocker Drive Encryption

Why Is the System Reserved Partition on the Wrong Drive

When Windows is installed on a blank disc, it creates a unique partition called the System Reserved partition. The Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and startup items that BitLocker requires are all stored on the System Reserved drive.

The System Reserved partition does not have a drive letter. Thus you can only see it via Disk Management or another similar program. The system partition and the system reserved partition in a computer share the same disk (usually the C: drive).

However, some users discover that after installing the system, the system partition and the reserved system partition are on different disks. The installation process accidentally creates this when the PC has several hard drives. So how do you handle a Windows System Reserved partition on the incorrect drive? Read on to find out.
