Question How do I get rid of a Win 7 Dual Boot?

[Caveman]

Current PC has Win 7 and 10 Dual boot. Everything is now working great on Win 10 and I want to reclaim all that drive space into the Win 10 partition. I don't care about 7 at all or all that was installed there.

I don't know where to start to make a single boot into Win 10. Can anyone help?

Go to disk management, type this into windows start or search to find it.
Expand it to show all of your drives in the lower part.
Post this picture here, if you don't know any service imgurl is free to use for this purpose, if you already use something else that will be fine too.
The point is that we will have to determine which drive and or partition windows 7 is on and where the boot files are located.
Since the boot files could be on the same drive as windows 7 just deleting the partition could cause your system to not boot into any windows anymore.
