I have a NON-UEFI laptop. However UBUNTU keeps detecting and wanting to install UEFI. Obviously the system never boots if I allow it to install in UEFI mode. Once a UEFI partition and installation has been created I can only boot from AMD64+MAC images, as standard images give me and "error file '/boot/' not found" and grub2 freezes and hangs up the machine. I can only reboot after that. I can however wipe the partition table and the LIVE USB installer will boot up just fine. What command line options can I give to tell it to install in BIOS BOOT mode and not UEFI?
