Cara Instal Win 7 Laptop Acer

Hi, everyone. I recently bought a HP 250 G4 laptop with FreeDos preinstalled on it. I tried installing Windows 7 from both a bootable USB and DVD with no success. Every time installation stops at 'missing drivers error'. I tried switching ports, changed BIOS boot sequence,(advanced options in BIOS are locked), formatted drive to NTFS, used legit ISOs from Microsoft website, tried to install drivers from another USB but I just can't seem to get it working. It's been 3 days already and I'm about to rip my hair out!
