Do a search on "install windows 7 on b360 motherboard". In my opinion, there are 2 issues, installation and sub-optimal drivers. Installing win7 off of a usb drive requires usb 3.0 drivers, which are not included in the win7 iso. Gigabyte use to have a bootable usb drive builder to slipsteam in the usb drivers in with the iso. However, I couldn't find it on their site anymore. Also, legacy bios, CSM and USB PS/2 emulation need to be enabled.
If you get win7 installed, then win10 drivers may work, but may not perform as well as on a win10 installation. Sort of a shame to have new hardware and have it not perform as well as it could. Besides, win7 is only going to be supported for another 1.5 years. I'd say bite the bullet and get win10...
