在Windows 10上恢复已删除的分区?

前言:我对计算机一无所知,我的行话可能是错的。

After downloading and installing Windows 10 Home today, I watched a tutorial on how to delete a recovery partition. I did this because the space (500 gb) of this recovery partition was not showing up in File Explorer. In this video, https://www.youtube.com/watch?v=N5v4kDzwVJc, at the end, the person "assigned" the unallocated space into the existing drive. I followed this video for each step. BUT the unallocated space was never added to the existing disk. I see all these tutorials, but each one never pans out. I tried following this: https://www.makeuseof.com/tag/recover-lost-partition-windows/. But it didn't work. How do I bring back this partition so that I can use the space that it had? Any help would be greatly appreciated. Help :3
