the boot repair info

boot repair is unable to fix the problem saying>
The boot of your PC is in Legacy mode. Please change it to EFI mode. Please use Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd) which contains an EFI-compatible version of this software. ((use it from live-USB, not from DVD))

Can I use the boot/repair advanced mode? how?

thx in advance
