I have an ASUS n550-jk laptop and I wanted to install Ubuntu 15.10 alongside Windows 10 (with dual boot) with UEFI. After going to booting menu and choosing boot option (I tried both bootable USB and bootable DVD), Ubuntu freezes after couple of minutes or seconds on the first page(ubuntu name with orange dots and purple background) and this thing happened in both situations(try ubuntu live or install it directly)
I also disabled fast startup , but I can't disable secure boot , because in bios menu there is no option for disabling secure boot , I also upgraded my BIOS but still there is no option for disabling it.
P.S : I also tried 14.04.4 LTS version but I had the same problem.
e
. This will enable you to edit the kernel options. Locate the line that includes the stringquiet splash
and remove those two words from the line. This will produce a more verbose boot. When the system hangs, take a screen shot with a digital camera and post the results. Be sure it's in focus and in high enough resolution to read it all.
