Installing a new mobo and CPU - how to perform an install of Windows without USB or CD

[mattpao2]

Is there a way to create a partition on my hard drive that has a "dormant" Windows 10 waiting for me to install it?
I want to: 1 - Install new mobo and CPU
2 - I don't have a CD drive or a USB with Windows on it
3 - If my computer won't boot with the new hardware, what can I do to reinstall Windows?

1, Do this before swapping hardware - reactivating win 10 on new PC and after to move licence.

2. download the Windows 10 media creation tool and use it to make a win 10 installer on USB or DVD
3. see 2
