I have a MacBook "Core 2 Duo" 2.2 13" (White-SR) 2.2 GHz Core 2 Duo (T7500) with single boot - Ubuntu 17.04 on.
I want to make a fresh installation of Lubuntu 14.04.1 LTS (mac) from a DVD.
I have tried to start the laptop holding the 'c' key down until the DVD drive starts and then release it but no luck. I also tried holding the 'option' key down and that gets me to a 'menu' with the only option to start from a hard drive named 'windows' (?) but no DVD drive option. If the hard drive is selected the system does not boot.
**pressing 'esc' during the boot process gets me to the grub menu and/or console. anything i can do from here? **
p.s. I also tried with another .iso CD that I know for sure works and did not get any results. so probably it's not the specific DVDisc that causes the problem.
thanks for reading!
