Recovery Partition After Upgrading to Windows 10 from Windows 7/8

After upgrading Windows 7 or 8 to Windows 10, you find an extra recovery partition in Disk Management. What’s it for? Can you delete it? This article will tell you all about recovery partition.

What Is Recovery Partition?

Recovery partition is a small partition on your hard drive that can help you restore your Windows or troubleshoot system issues. There are two kinds of recovery partitions you may see in Windows 10/8/7.

Windows recovery partition

When installing a Windows operating system (OS) on a hard drive, and if you use Windows Setup to create new partition on an MBR disk, Windows will create a system reserved partition, and if it is a GPT disk, then Windows will create a recovery partition and an EFI system partition without drive letter. The recovery partition on Windows 10 consumes about 450MB, Windows 8/8.1 200MB, and Windows 7 100MB.

This recovery partition is to hold the Windows Recovery Environment (WinRE), which can be explored if you manually assign a drive letter to it. If you delete this partition, you won’t be able to use Windows Recovery options. If you create Windows 10 recovery disk, Windows will give you an option to remove the recovery partition. With the recovery drive, you can still use Windows recovery options. Otherwise, if you install Windows on a hard drive containing multiple partitions, Windows will save the WinRE in a folder named Recovery in the root directory of your system drive (C: drive) without leaving a recovery partition.

OEM recovery partition

Apart from the recovery partition of Windows, there may be another recovery partition created by the computer manufacturer like Lenovo and Dell that has made their computer comes with an OEM recovery partition consuming about 7 to 20 GB, which contains the WinRE and their factory installation files.

On some computers, the WinRE and the factory installation are separately stored on two partitions, so you may see two OEM partitions on your computer. This OEM partition allows you to press a specified key to boot into Recovery Environment, so you can recover your OS to factory setting without a Windows installation disc. If you have a copy of Windows installation, you can delete this OEM partition to free up more disk space.

Why An Extra Recovery Partition Created During Upgrade?

Every time when you upgrade Windows to the next version, the upgrade program will create a recovery partition if it detects that there is no sufficient space on your recovery partition (GPT disk) or system reserved partition (MBR disk). There is no wonder that you have many recovery partitions after upgrading to Windows 10. If you don’t want Windows to create another recovery partition, you can increase the size of recovery partition or system reserved partition before upgrading to Windows 10.

According to Microsoft, the previous Windows version recovery partition will be nonfunctional, so you can delete the previous recovery partition to free up some disk space. As you may know that Windows can only shrink a partition from its right side, so you can tell which recovery partition was newly created by upgrading to Windows 10. For example, as the screenshot below, the 100MB recovery partition was created when installing Windows 7, the 200MB recovery partition was created when upgrading Windows 7 to Windows 8, the 500MB recovery partition was created when upgrading Windows 8 to Windows 10, and the OEM recovery partition created by PC manufacturer before shipping.

As you see the new created Windows recovery partition stands in the way of extending system partition. If you do not want to delete the recovery partition, you can move Windows 10 recovery partition without data loss.

How to Delete Recovery Partition in Windows 10?

You cannot delete a recovery partition with Windows 10 Disk Management for it has crucial files, but you can use diskpart.exe to delete recovery partition. However, you still cannot extend the remaining partition with the new created unallocated space if the recovery partition appears before the C: drive. Hence, you need third-party partition software to do this job. AOMEI Partition Assistant Standard, a free partition software, can delete the recovery partition and extend a partition as long as there is unallocated space on the disk.

1. Download this free software. Install and launch it.

2. Right-click the recovery partition you want to delete and select «Delete Partition». Then you can see the recovery partition becomes an unallocated space. Actually no changes will be made until you confirm and click Apply.

3. Click «Merge Partitions«. In the pop-out window, check the unallocated space and the partition you want to extend.

4. Check the pending operations and click «Apply» and «Proceed» to save the changes.

This operation will complete under AOMEI PreOS mode, so do not be panic when your computer reboot.

How o Create A Recovery Partition?

Many users have met the problem that OEM partition won’t work after upgrading to Windows 10. What to do when you want to use recovery options only to find you have mistakenly deleted the recovery partition? You can use AOMEI OneKey Recovery to create a recovery partition on Windows 10 to backup and restore your current system including all the programs installed on C: drive. It also allows you to press a specified key “F1” or “A” to boot into AOMEI OneKey Recovery environment when your computer starts.

After creating the recovery partition, you can also keep the system backup image files in other locations besides the recovery partition, which means you can keep many system backups at the same time. When system fails to work, you can just press the Specified key to boot into AOMEI OneKey Recovery and select the system backup to restore system.

The recovery partition after upgrading to Windows 10 won’t consume much space on your hard drive, so it is recommended to leave it be. If you really want to get rid of recovery partition, backup essential files before deleting.

Info for Windows Insiders

If you’re an Insider and the current preview build isn’t working for you, select the Start button, then select Settings > Update & Security > Recovery . Under Go back to the previous version of Windows 10, select Get Started.

Going back to an earlier build won’t remove you from the Insider Program. When the next preview build is ready, it’ll be installed on your PC.

This option takes your PC back to an earlier point in time, called a system restore point. Restore points are generated when you install a new app or driver, and when you create a restore point manually. Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.

In the Control Panel search box, type recovery.

Select Recovery > Configure System Restore > Configure and see if the Turn on system protection option is selected.

If the Turn on system protection option is selected, continue with step 6.

You’ll see a list of items that will be deleted if you remove this restore point. If you’re OK with the deletions, select Close> Next > Finish.
