Ubuntu 15.04 installation gets stuck at loading screen
I had the exactly same problem. Disabling Fast Boot AND CSM got me throught the to the installation. Without Fast Boot I got to the loading screen, but then it got stuck. I read this and as far as I understand, CSM allows non-UEFI installations. Since I have Windows 10 already installed and booting fro UEFI and want a dual boot, I tried disabling CSM et voilà, I am installing ubuntu 15.10 on my ASUS N552VX as we speak.
Hope it works for you too.

When I boot from the USB stick with Ubuntu 15.04 on it, I'm offered with the choice of trying Ubuntu or installing it directly. Neither of those work as in I don't get past the loading screen. Before that, there are some messages with one of the first ones being
ACPI PCC probe failed
but the internet™ says, it's fine. Also I get reoccurring errors like these (seems to be related to my graphics card):[ 50435508] nouveau E[ PFIFO][0000:03:00.0] SCHED_ERROR [ UNK06 ]
I’m completely lost and don’t know where to start now. Any help is deeply appreciated. How can I install Ubuntu on its own partition?
The Setup
- Operating system: Windows 8.1 (64-bit) that was pre-installed on an Acer laptop (UEFI)
- Graphics card: Nvidia GeForce GTX 850M
- Boot Mode: EFI / Partition style: GPT (Identifying which boot mode the OS uses)
- Fast Startup and Secure Boot are disabled
- There is free space on my hard drive which is not yet partitioned
- Windows 8.1 installation disk in case I need to repair something

Rod Smith over 8 yearsFirst, I've seen a lot of problem reports about the tool you used to create the Ubuntu installer. I suspect that it creates images that are unbootable in EFI mode. I'd try something else, like Rufus. Second, it's imperative that you install both OSes in the same mode (BIOS/CSM/legacy vs. EFI/UEFI). To do that, you must know the Windows boot mode. See this page of mine for information on how to do that.

kleinfreund over 8 years@RodSmith I will try Rufus. Also, I added the information about the boot mode to the question. It's EFI.
