Trouble installing win 7

[fitz159872]

So I've recently decided to install windows 7 on my PC (Currently Windows 10), and I've been unable to install because all my USB ports are not supported by Win 7. Any suggestions?
I've considered installing windows 7 on an older system and installing drivers before moving the HDD to my main, any thoughts?

Motherboard: Z370-E
CPU: Intel i7-8700k
Edit: As someone mentioned(Thank you), my chipset and motherboard is not compatible.

Your chipset and processor do not support anything other than win10, so you are going to have to make the move from 7.

What is the motherboard? Many 300 series motherboards are not compatible with Windows 7.

To install windows 7 on Z370 board, you have to integrate usb drivers into installation (plus nvme drivers, if you want to use nvme drive).
You can do that with gigabyte windows usb installation tool.
