Error "ACPI motherboard layout requires EFI" when setting ESXi 8.0 VM to BIOS

[EpicLPer]

Hello,

I've recently set up ESXi 8.0 and migrated my VMs over, however I noticed when I tried booting VMs (no matter if Windows or Linux) and set the boot option to "BIOS" I'm only getting the error as in the title: "ACPI motherboard layout requires EFI"

I haven't found anything about this error anywhere. I've also already tried various settings that I thought might help, but so far had no luck. There isn't anything I can change about any motherboard layout at least in the Web GUI, is there anything else I'm missing? On ESXi 7.x this worked just fine still.

Thanks for your help already!

A very late reply but this just fixed the issue! Totally forgot I made this forum post, and found it again when trying to set up a new Linux VM. I simply set it up in BIOS mode from the beginning and this fixed it, thanks 🙂
