Installing Drivers on Downgraded Laptop

Hey folks,

I have just bought an Acer E5-575, which comes with Windows 10, however it's kinda slow, especially when I connect to the Internet. I've set the wifi to metered, but it's still too slow. So I installed Windows 7 on the other partition, but I'm having problem with installing its drivers, especially graphics as most of them are compatible only with Windows 10. I would really appreciate it if you could help me out with this.
