0x07d0 is an offset for what? memory? boot sector?

Should this NTLD field be blanked by someone coding a boot sector?

Is this a standard BIOS machine or UEFI?

Any idea on what is loaded in extra BIOS? boot loader? UEFI?

Does this NTLD field have anything to do with your issue?

Are you sure your BIOS is not infected?

BIOS rootkit

Is this something to do with Secure Boot?

Secure Boot disables a BIOS CSM module for normal booting.
This is supposedly for UEFI v2.3.1 Errata C or later.

Could this CSM module be the other version of BIOS that you're seeing?

Apparently, UEFI can't be disabled on newer PCs.

Does anyone know if UEFI Secure Boot on new motherboards is preventing
older Linux distributions from being installed?

Does anyone know if newer PCs cannot boot custom boot loaders?
