How did you upgrade to Windows 10, upgrade through MS's free upgrade?
When you format a hdd/ssd it remove data from the drive.
If you wish to use Windows 10 you can use the Media Creation Tool
to create Windows 10 installation media for a disc or flash drive.
There are three options, use the second option Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on different PC
If you had successfully installed Windows 10 and activated it you will not need to activate the new installation as long as the version you install is the same which was installed previously.
Can you at this point boot into either operating system to run test programs?
