In case you’re trying to update the firmware on your Intel SSDs by using their handy dandy issdfut Version 3.0.7 or 3.0.8 ISO just to be greeted by an ISOLINUX error like
Failed to load ldlinux.c32
Boot failed: press a key to retry…
Chances are it’s because their ISO seems to be broken when booting using legacy BIOS mode. Switch to UEFI and it will most likely work the way it’s supposed to.
When you’re done, don’t forget to switch back to legacy BIOS if you installed your OS that way, otherwise it probably wont be able to boot.
