That laptop officially supports only Windows 10-64 bit. You might get some undesired errors from time to time.
You might be able to get Windows 7 by disabling Secure Boot, and enabling CSM.
Place the Windows 7 USB and hit the Esc key and select to boot from the USB flash drive.
You could Also select to boot from the USB in the BIOS.
