I suspect your installation media has something wrong.
Visit the following website and download media creation tool, use tool to download original Windows 10 iso image, then use it for installation, note 32-bit or 64-bit. 32-bit Windows 7 can only use 32-bit Windows 10 iso for upgrade.

Also, the iso from media creation tool can be used for creation new VM in Hyper-V
