Q:

fresh installation only shows a "dash"

I have just installed ubuntu 14.04 on my old macbook. Installation was succsessfull. There was an error befor booting: efi wasn't loadable. I fixed that. But Ubuntu doesn't start.
I only see a dos cursor (don't know the name) "  -  " <-- 
And it is blinking. Thats all. I tried changing my Touchpad configuration... because that worked before. (Don't ask why. The world is mysterious.)
Does anyone have an idea? :)
Greetings Meee
PS: 12.04 works just fine

A:

I just startet to rebuild my laptop OSs again. 
I now have a solution to the Problem I ddiscribed. The "dash" implicates that the efiboot-partition is missing/not bootable. Ubuntu doesn't create it on its own. The Installaion was fine. To fix the boot error the Partitiontable had to be selfmade. Important is a efiboot-partition in the beginning of the boottable. Now Ubuntu works fine and starts without a Problem.
For everybody that isnt sure if his Macbook / MacbookPro has all the needed firmwareupdates:
Go to: 
http://support.apple.com/en-us/HT201518
You have to use Mac to install the firmware. (I installed it on an extra harddisk)
The message Efi/Boot/fallback.efi 14 isn't important. 
Have a nice day!
and thanks for your Help!
