Cannot Boot Fedora 23 live media on Lenovo C540

[R Mercado]

I have now been able to validate the Live Fedora CD by booting it on an
older machine. The Lenovo C540 does not boot with it though.
Thanks to Chris Murphy's suggestions I also got a bootable USB stick.

The Lenovo picks up some of the boot code and comes to a menu where i
can choose "Start Live CD", "Verify media and start live CD" and
"Troubleshoot".

Selecting "start live CD" the machine shows a black screen with a
blinking cursor at the top left and freezes. The keyboard
NumLock/CapsLock LEDs stop responding to toggle. Ctrl-Alt-Del work when
frozen.

I could not find Lenovo firmware updates to flash the BIOS.

I initially installed Fedora 20 on the Lenovo C540 and I remember the
installation media used to work okay on it.

Thanks,
RM
