The recovery partition is a small partition on your hard drive that can help you restore your Windows or troubleshoot system issues. When installing a Windows operating system (OS) on a hard drive, and if you use Windows Setup to create a new partition on an MBR disk, Windows will create a system reserved partition. The recovery partition on Windows 10 consumes about 450MB, Windows 8/8.1 200MB, and Windows 7 100MB.
Unfortunately, Windows won’t let you delete the recovery partition in Disk Manager. When you try right-clicking on it, it doesn’t have any delete option.
To save some space, here are a few step to delete the unwanted partition:
Open Command Prompt (cmd) under administrator privilege
Type diskpart then hit Enter
Type list disk to list all physical drive that presents in your computer.
Type select disk and the number of the disk. In my case I choose Disk 2, you may look into Disk Management under Computer Management then you will see which disk you need to select.
Type list partition then you will see the Recovery Partition there
Type select partition and the number of partition. You must ensure that select the right partition type “Recovery”
The important step, please verify all the command you’ve entered above are correct before going to the last step.
Type delete partition override, this step will delete the selected partition.
Once the deletion is complete, your Recovery Partition must be gone way then you will get back some space.
Hope it help, thank you for reading.
