In the event of a system error where your computer cannot boot, the recovery partition holds data that allows you to restore to factory settings.
Many dislike it and would prefer to delete it entirely. Others like the idea of having a recovery solution that’s ready to go if anything happens.
If your recovery partition has been corrupted, the only way to create a new one is by reinstalling Windows. Before doing so, it goes without saying that you should back up all necessary data before resetting anything.
Right-click the Start button and select Settings.
Click Update & Security.
Click Recovery.
Under Reset this PC, click Get started.
When reinstalled, Windows will create a backup partition again by default.
