I googled your notebook and it says it comes with Windows 8 by default. So i'm not sure if updating your BIOS is needed.
Try one of these ISOs.
Edit: the digital river win7 isos links no longer work =[
He needs to flash the BIOS, and then set ACPI to version 3.
BTW - he may have bought the laptop without the OS. You can save a few dollars doing that. But if you are clueless at installing an OS, it is better to spend those "saved" dollars and get it with the OS already installed.
EDIT 2 - the old Digital River links have been removed by MS. They now require you to input a valid serial key before you can download any version of Windows starting with Vista. If you do input a valid key, the downloads are super fast. I downloaded Win8 in about 35 minutes (using a 150 mbs pipe).
