How did you install the bootloader? Is your board switched to legacy
mode if that is what you are using? If using UEFI do you have both
BIOS and UEFI boot flags set?

The error you gave is what the motherboard firmware would display if
it can't find any bootable drives. Some firmware (like Apple's) will
only boot a UEFI partition if the enclosing protective MBR also has
the partition marked as bootable.
