Fedora 20 installation on Lenovo N500 fails

[Kevin Wilson]

Hello all,
I tried to install Fedora 20 on Lenovo N500 laptop (x86_64) from a DVD.

I verified the DVD media and also I had installed a desktop today with this
DVD.
When I try to install it on Lenovo N500 laptop (x86_64) it fails - it reboots.
I tried several times.

I also tried in text mode ("linux text") and again it fails.

Any ideas ?
Regards,
Kevin
