I have been having this issue for the last two day, Im attempting to install ubuntu gnome 14.04LTS, it appears to go through with the installation fine, I customize everything as far as desktop settings and other stuff to my liking and then soon as I restart my computer it wont boot, I have wiped the partition and reinstalled 14.04LTS several times and it does the same thing everytime! If I install Ubuntu Gnome 16.04LTS it works fine and restarts and boots like normal but as of right now using 16.04LTS isnt really a option because the main program I want to use isn't compatible with 16.04...

Ive attached a picture of the screen it gets stuck at everytime I try to boot ubuntu gnome 14.04LTS

The kernel thats installed is 4.2.0-27-generic



--- THINGS I SHOULD MENTION --

- I have this dual booted on my macbook pro retina mid 2014

- I didn't make a partition for swap as I have 16gb of memory and figured i could go without(and 16.04 boots fine so I don't think this is the issue)

- I didn't install grub, I hold option key down and and just select the ubuntu partition(Dont think this is a problem as 16.04 boots fine doing this without grub)


Does anybody know what the issue could be??

Hi...

Welcome to the forum

This might have something to do with the graphics chip. By any chance, does using the nomodeset parameter help?

Hello and welcome to LQ.

You won't need a swap partition. It isn't the cause.

I don't know much about Apple stuff but I kind of wonder how you got 16 to work without a loader. When you choose the option key to select 16 try to press the space bar to try to catch grub if it is loaded. Then you could possibly edit grub to boot 14, That isn't the way you want I understand just a test.

So, now that I say I don't know apple stuff, how can you get the option key to boot 16?? Maybe I should ask that first.

I dont even have grub installed, I dont use it at all, I dont know what it is, since ive posted this, i have installed 16.04 again and now 15.10 and they both work fine when booting up with the option key, Ive had 14.04 installed on my mac before a while back but I was using refind so I dont know if its ever worked with the option key, but I really dont want a bootloader because I honestly dont plain on using ubuntu that much really just to emulate ps2 games so I dont want to see the ugly boot screen everytime I start my cpu.... I honestly dont know what the issue is but for now im just using 15.10......

Hi...

If you've installed Ubuntu to your hard drive, then you have a bootloader. And you need one to even boot Linux at all. Please give our suggestions a try and tell us what you find.
