Hi I have this problem and it is very frustrating. I downloaded 64 bit ubuntu 14.04 and make both DVD and USB drive from the ISO file.
I want to install Ubuntu alongside with my win 8.1. When I choose to boot from USB/DVD under UEFI mode, I can see to options to try or install ubuntu. But if I select one of them, I just see a black screen and it stays that way forever.
SO I can never actually install Ubuntu because I cannot even see the installation screen!
I turned off fast boot in win 8.1 and secure boot in UEFI. I do not know what causes the problem. I built this desktop by my own and the motherboard is Asrock Z77 and CPU is 3570k.
Can anyone help me with this problem? I really need to use ubuntu.
Thank you so much!!
