Bios Update on Novatech PC-CX00915

Hello I am looking for the latest bios update for the above PC model as currently when I try to run a bootable USB to install Windows 7 (Currently built as Windows 8.1) it ends up blue screening saying ‘this bios in this system is not fully acpi complain please contact your system vendor for an updated bios’.

Could someone provide me with this please?

This is not likely to be an issue with BIOS version but more likely BIOS settings. Windows 8 and Windows 10 preloaded from OEM will have secure boot enabled and CSM Functions disabled. This is to meet Microsoft requirements with regards to those OS and also shipping unit in UEFI Mode.
In the BIOS if you want to use Windows 7 you will need to make sure that secure boot has been set to disabled and that CSM has been enabled. Without these functions Windows 7 will not work.

Can you let us know if you have configured BIOS correctly for use with Windows 7 OS already??
