Many people are facing this annoying issue while trying to install Windows 11 in their computer systems and unable to upgrade to Windows 11.

Removing or Fixing System Disk Needs to be 64 GB or Larger Error:

The 3rd one i.e. “The system disk needs to be 64 GB or larger” message occurs if the system drive or partition on your Hard Disk drive (HDD) is less than 64 GB.

Many computer systems contain C: drive of 50 GB or less and since Windows 11 requires at least 64 GB space in system drive i.e. C: drive, you get the “The system disk needs to be 64 GB or larger” error message at installation time.

So how to resolve the problem? Very simple! You just need to increase the size of C: drive to 64 GB or larger.

In past, we required to use 3rd party partition manager software to modify hard disk partitions but now the built-in Disk Management tool in Windows 10 allows you to manage hard disk partitions easily and quickly without using any extra software program.

Using Windows 10 Disk Managements tool, you can:

• Create partitions
• Delete partitions
• Format partitions
• Resize (shrink/extend) partitions
• Change partition/drive letter

We’ll need to extend C: drive size and we can use Disk Management tool to do the task. It’s very simple and fast.

Following steps will help you in resizing C: drive to make it 64 GB or larger to run Windows 11:

STEP 1:

Press WIN+R keys together to launch RUN dialog box. Now type diskmgmt.msc and press Enter key. It’ll open Disk Management tool window.

STEP 2:

Now you have 2 choices:

• OPTION 1: Delete an existing partition and add the free space to C: drive to make it large
• OPTION 2: Shrink an existing partition and add the free space to C: drive to make it large

First option is the easiest one. If you have an extra partition or drive which is not important, you can delete it and then you can add the available free space to extend C: drive.

But if you don’t have any extra partition or drive which can be deleted, in such situation, you’ll need to shrink an existing partition to create free space and then add the free space to C: drive to make it large.

OPTION 1:

If you have an extra partition or drive which can be deleted, right-click on the partition and select “Delete Volume” option.

Windows will show some warning and confirmation dialog box, click on YES button in all boxes.

Now right-click on C: drive or partition and select “Extend Volume” option. It’ll open Extend Volume Wizard. Click on Next, Next and Finish buttons.

That’s it. It’ll immediately increase size of C: drive. You can check the new size in File Explorer or This PC.

OPTION 2:

If you can’t delete any existing partition, you’ll need to decrease size of an existing partition to create free space to add it to C: drive.

Right-click on another partition which contains extra free space and select “Shrink Volume” option.

It’ll open Shrink partition dialog box.

Now in 3rd text box “Enter the amount of space to shrink in MB“, enter the size which you want to take from the partition in MB. For example, you can enter 40000 to take 40 GB space from the partition as shown in following screenshot:

Click on Shrink button and Windows will resize the partition.

Now right-click on C: drive or partition and select “Extend Volume” option. It’ll open Extend Volume Wizard. Click on Next, Next and Finish buttons.

That’s it. It’ll immediately increase size of C: drive.

That’s it. Once you enable TPM, Secure Boot options and increase C: drive size, again open Windows Update page and click on “Fix Issues” button.

Now you’ll no longer receive “This PC can’t run Windows 11” error and Windows 11 will download and install without any problem as shown in following screenshot:
