If you mean how to run iOS on a laptop that has already Windows 10 installed on, so all you need is to resort to a Virtual Machine to be able to run a second different OS on same one laptop.
For this, there are 2 different common Virtual Machines:
1. VMware Workstation,
2. Oracle VirtualBox.
In my case, I'm using VMware Workstation:
but to run Kali Linux OS, not for iOS:
Yet, it's the same process. In your case, you'll need to download a Virtual machine and iOS image (.iso) and you'll be all set to run iOS on your laptop.
