Most Acer Aspire V3-772G pre-installed with Windows 8, and Acer support site provides Drivers only for Windows 8 , Windows 8.1 and Windows 10. Not all Windows 8 drivers will work on Windows 7. The other problem is you can't install Windows 7 without changing the UEFI BIOS into Legacy BIOS. You can change it by power on your V3 and press F2 repeatedly until you see BIOS screen pop-out. Using arrow key on your keyboard select BOOT on top, and on BOOT mode select Legacy.
After that, press F10 to Exit and save changes. You computer will restart and you can continue with Windows 7 installation.
