OK, that *is* strange. I'm curious - do you have secure boot enabled,
maybe?
Right. So it's booting grub, but not getting any further at all. Have
you copied all the files from the CD image? I'm wondering if it's
maybe not finding some things it's looking for, or (alternatively) it
may be failing to set up a working video mode.
