Hit “Next” once you have finished all of this. Most of the time, leave these to defaults. The file system, unit size, and volume labeling will then need to be established. Choose the “Format this volume using the following settings” option.

You will be prompted to format the drive.

After choosing “Assign the next drive letter,” choose the drive letter.

Your next options are to set the drive letter or mount it in the empty NTFS folder.

You won’t be able to exceed the limit here, but you can set a custom size.

The “Simple Volume Size” (in MB) input field will be presented to you.

This will launch the “New Simple Volume Wizard.” Select “Next.”.

Click “New Simple Volume” from the context menu by right-clicking the unallocated space.

You must now build a new basic volume for the space.

To delete a volume and make it unallocated space, right-click the problematic volume or drive and choose “Delete Volume.” The drive will successfully be labeled as unallocated space once you’ve done this because a black bar will appear on top of it.

If it’s already labeled as unallocated space, skip the next step.

You must make the drive’s primary partition unallocated space.

The primary partition will have a blue bar on top, while the unallocated space will have a black bar.

Verify whether the drive is the primary partition or already an unallocated space in Disk Management.

Click on the “Windows key + X,” and then choose “Disk Management” from the list.
