Hi all,

i try to fresh up my old mac pro with ubuntu or lubuntu, kubuntu but i get stuck all the time
Tried Matt Gadients Guide but fails "srst failed (errno=-16)"

best way so far was sergems Blog with ubuntu 14.04. USB stick, but I am lost at how to choose the kernel theres literally hundrets.
Problem: Install complete successfull but black screen. all other versions failed at the bootmanager, it cant recognize the install.

theres a hint to update grub after installation process is done, any hint how I can do this?
