Somehow managed to install Windows 10 without uninstalling Windows 7

Ok, so I thought I was upgrading from Windows 7 to 10, but when I installed it, widows 7 is still installed. How do I get rid of windows 7? And not just untinstall, but also reclaim that hard disk space?

Thanks

 

Hi, to remove existing Windows 7 refer to https://kb.parallels.com/5029 . Thanks, Abhishek.

 

I found that article, but when I right click, I do not get the option to "Remove"...?

 

I called support, and they found that Windows 7 was running in the background. They opened Activity monitor, did a search for Windows 7, and did a force quit on it. Once complete, the option to remove Windows 7 appeared as described in the Knowledge Base Article. Thank you.

 

Hi, we are glad to know the issue was resolved over remote session with our support team.
