I just set Vbox boot order to HD > CD/DVD. And added a new blank VDI for the HD, and a Fedora 22 Live CD ISO for the CD. And it boots from the CD. So the HD is clearly skipped. If I partition the HD with fdisk with a single partition and no boot flag, I get the same result. So clearly this BIOS is also ignoring/skipping the HD when bootloader code in the first 440 bytes is absent but otherwise has a valid signature and partition information. If I partition a new blank VDI with parted, boot hangs indefinitely with no error message.
