Windows IoT on the Raspberry Pi is only supported with a regular Intel x86_64 based laptop (or desktop) running Windows 10. Anything else would need some serious hacking (which won't be possible).
If you join the Windows Developer Insider Program you may still be able to get the upgrade from Win7 to Win10 for free (take a full backup first in-case that doesn't work on your ancient hardware).
