Is your computer running a 64-bit operating system? Windows 7, or upgraded to Windows 10 after 2015?

Can you boot into BIOS Setup, and enable virtualization? Given the vintage of the computer, it might not even be an option.

There is a 32-bit version of Windows 10. Is that the OS that you are trying to install?
Note that Windows 10 64-bit requires a minimum of 2GB of RAM. In your case, how much "real" RAM does your hardware have? Hopefully, you have at least 4 GB (2 GB for the "real" OS, and another 2GB for the virtual OS to use).
If not HyperV, maybe try the Oracle VM hypervisor ?
