Deleting a "System Reserved" partition

Hello,

Thank you for bringing up your query on Microsoft Community.

We sincerely regret for the inconvenience caused.

Please be assured that we will do our best to help you.

• 
  What happens when you try to delete the System Reserved Partition?
  
• 
  Do you receive any error code/message? If yes, what is the exact error code\message you get?
  

I suggest you to start your computer in safe mode with Networking and check if you are able to delete the System Reserved Partition.

Safe mode is a diagnostic mode that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started.

Refer the article below:

Start your PC in safe mode in Windows 10

The system reserved partition contains boot files, you may create a recovery drive before deleting it.

Hope it helps.

Kindly let us know if you need any further assistance with Windows. We are happy to assist you.

 

Deleting system reserve

Using a third party tool, it suggests that there are no consequences for deleting the 16MB system reserve and that this will allow the EFI system partition to be increased beyond its current 100MB (lack of size has hindered standard updates of Windows
10). I have over 300 MB of unallocated disk space that I can add to the EFI system partition.

 

System Reserved Memory issue

Hi Rowan,

The reduction in available system memory depends on the configuration of the following:

• The devices that are installed in the computer and the memory that is reserved by those devices
• The ability of the motherboard to handle memory
• The system BIOS version and settings
• The version of Windows 10 that is installed
• Other system settings

As an initial troubleshooting step, I suggest that you check your system for memory problems.

Here's how:

• Type mdsched.exe in the search bar and select the best match.
• When prompted by the User Account Control, enter an admin user name and password, and click
  Yes.
• Follow the on-screen instructions to run it.

Let us know how it goes.
