this messed my whole computer.no cant even load windows. im now stuck with a computer that just boots to bios

That is just because you need to know more about tinkering around a BIOS is all.
I am surprised you wanted to crossflash to another BIOS that wasn't for your system without even knowing your way around a BIOS
Next time you have pre-built system, be sure to only update to the correct model BIOS, but even then you need to take images of all the BIOS, all pages, all settings etc, so you can reset everything back after BIOS update is done
