Formatted my recovery partition

I accidentally formatted my recovery partition. How can I restore it?

Welcome
You do not want to restore the partition. Even if you were able to, at best, in the event of a problem, you would go back to the way the computer was the day you took it home. If you download the free Macrium Reflect, and make an image, saved to an external hard drive. In the event of a problem you can restore to the way you were at the point that you made the last image. If you make a new image once a month and you have a problem, you will not have to reinstall software, updates etc. This is very much easier.
