How increase size of system reserved partition in order to update Windows 11

Answer 1

Hi ,

You will do the following: download the Minitool Partition Wizard Portable version and then run it as administrator > After opening it, go to drive C > right-click > select Move or resize > remove 100 MB > press OK > and apply > wait for the process to finish and restart the computer.

After the above process, Minitool Partition Wizard will open again. Select the 100 MB partition on disk 0 > right-click and select Extend and extend using the 100 MB that we removed from drive C, click OK and apply.

Restart the computer and try to restart the update process.

Search for cmd. Press-and-hold or right-click on Command Prompt in the results, and select Run as administrator.

At the command prompt, type mountvol y: /s and then hit Enter. This will add the Y: drive letter to access the System Partition.

Switch to the Y drive by typing Y: and press Enter. Then, navigate to the Fonts folder by typing cd EFI\Microsoft\Boot\Fonts. Once there, type del . to delete font files. The system may ask you if you are sure to continue, press Y and then Enter to continue.

To increase the size of the System Reserved partition in order to update Windows 11, you will need to follow some manual steps. Here’s how you can do it:

1. Check the Current Size: First, you need to determine the current size of the System Reserved partition and see if it has enough free space. You can do this using the Disk Management tool or Command Prompt.
2. Create Free Space: If the System Reserved partition does not have enough space, you may need to shrink adjacent partitions to create unallocated space next to it. This can be done using Disk Management or a third-party partition management tool.
3. Extend the System Reserved Partition: Once you have unallocated space next to the System Reserved partition, you can extend it. This can be done using the Disk Management tool by right-clicking the System Reserved partition and selecting the option to extend it.
4. Use Command Line Tools: Alternatively, you can use command line tools such as diskpart to extend the partition. Here’s a brief command sequence:
   • Open Command Prompt as an administrator.
   • Type diskpart and press Enter.
   • Use list disk to see all disks, and select disk X (replace X with the disk number) to select your disk.
   • Use list partition to see all partitions, and select partition Y (replace Y with the partition number of the System Reserved partition) to select it.
   • Finally, use extend to increase the size of the partition.
5. Follow Additional Guidance: For specific scripts or further guidance on resizing the partition, you can refer to resources that provide detailed instructions on extending the Windows Recovery Environment (WinRE) partition, as it may be similar to the System Reserved partition.

By following these steps, you should be able to increase the size of the System Reserved partition and proceed with your Windows 11 update.
