Command prompt, diskpart, list drives, list volumes, select volume x, clean.

 

Just select the volume that 10 is an clean it. Then expand the other volume via the tool you're currently using.

I was going to do that, but I just went back to msconfig and made Windows 7 the default OS under the boot tab and then went to disk management and deleted the Windows 10 partition, then of course, expanded my Windows 7 partition. Restarted and it booted straight into Windows 7 and Windows 10 is completely removed! Thanks for your help though.

Okay, so here is the situation: I have Windows 7 and dual booted the Windows 10 Tech Preview and I want to uninstall the Windows 10 Preview from my system (no important files on Windows 10 partition anyway).

 

The problem is when I go to Disk Management it shows the Windows 7 Partition as: Healthy (System, Boot, Page File, Active, Crash Dumps, Primary Partition) and shows the Windows 10 Partition as: Healthy (Primary Partition). 

 

Then, when I go to System Configuration (msconfig) and boot tab, it shows that Windows 10 is the default OS and Windows 7 is the Current OS. 

 

All I want to know is how I can delete Windows 10 Tech Preview safely while keeping my Windows 7 partition for the highly anticipated Windows 10 launch. 

 

 

I would appreciate everyone's help with my issue. Below are images of both Disk Management and System Configuration.
