Windows XP ACPI Error – Cannot skip with F7

I am installing Windows XP x64 on an HP Laptop (DO NOT ASK WHY) and then I get to Setup is Starting Windows in the installer, “I get the BSOD saying The BIOS in this system is not fully ACPI compliant.”, I press the F7 key but it goes on with these options: “Other”, “ACPI Uniprossesser” and “ACPI Multiprossesser”, I select ACPI Multiprossesser and it gives that same ACPI error, Uniprossesser wont work because I have 2 cores.
