When you install Windows 11 on an SSD, a small System Reserved Partition is usually created. This partition contains important files needed for system boot and recovery. Sometimes, this partition might not show up in File Explorer or Disk Management, causing confusion.
Not being able to see the System Reserved Partition can make it difficult to manage your disk space or troubleshoot boot issues. However, this problem is often simple to fix with a few basic steps.
In this guide, we will walk you through clear, easy-to-follow instructions to help you make the System Reserved Partition visible on your SSD in Windows 11.
Follow along carefully, and you’ll have your system running smoothly in no time.
Quick Note Before You Start
- Make sure you have administrator rights on your Windows 11 PC.
- Check if the System Reserved Partition is already present but hidden using Disk Management.
- Be cautious when modifying partitions; incorrect changes can affect your system’s boot ability.
- It’s a good idea to back up important data before making any changes to your disk.
Step 1: Open Disk Management to Verify the Partition
The first step is to check if the System Reserved Partition exists but is hidden.
- Press Windows + X on your keyboard.
- Select Disk Management from the menu.
- Look for a small partition labeled “System Reserved” or a partition without a drive letter, usually around 100 MB to 550 MB in size.
If you see the partition without a drive letter, it means the partition exists but is hidden from File Explorer.
Step 2: Assign a Drive Letter to the System Reserved Partition
Assigning a drive letter allows you to access the partition in File Explorer.
- In Disk Management, right-click on the System Reserved Partition.
- Select Change Drive Letter and Paths…
- Click Add.
- Choose a drive letter from the dropdown (for example,
S:). - Click OK to assign the letter.
Now, check File Explorer. You should see the System Reserved Partition listed with the new drive letter.
Why Assigning a Drive Letter Matters
The System Reserved Partition is hidden by default to prevent accidental modification. Assigning a drive letter temporarily makes it visible for management purposes. It’s safe as long as you don’t delete or modify its contents.
Step 3: Use Command Prompt to Check Partition Status
If Disk Management doesn’t show the partition or you encounter errors, try using Command Prompt.
- Press Windows + S, type
cmd, right-click Command Prompt, and select Run as administrator. - Type
diskpartand press Enter to launch the disk partitioning tool. - Type
list diskand press Enter to see all connected disks. - Identify your SSD by its size, then type
select disk X(replaceXwith your SSD number). - Type
list partitionto see all partitions on the selected disk. - Look for the System Reserved Partition, usually marked as “System” or with a size around 100–550 MB.
- Type
select partition Y(replaceYwith the partition number). - Type
assign letter=S(or any other letter you prefer) to assign a drive letter. - Type
exittwice to close diskpart and the command prompt.
Check File Explorer again to confirm the partition is visible.
Step 4: Check and Repair the Partition Using Windows Tools
If the System Reserved Partition is corrupted or missing, repairing it can help.
- Open Command Prompt as administrator.
- Run the following command to check the file system of the assigned partition (replace
S:with your drive letter):
chkdsk S: /f /r - This command checks for and fixes file system errors and bad sectors.
- Wait for the process to complete, then restart your PC.
This step ensures the partition’s integrity and helps Windows recognize it properly.
Alternative Method: Use Third-Party Partition Software
If built-in Windows tools don’t resolve the issue, you can try third-party partition managers like MiniTool Partition Wizard or EaseUS Partition Master.
- Download and install a trusted partition manager.
- Use the software to view all partitions on your SSD.
- Assign a drive letter to the System Reserved Partition if it’s missing.
- Check for partition errors and repair if needed.
Third-party tools often provide more detailed information and additional repair options.
