I attempted to install 14.04.5 LTS yesterday on my laptop and as it got to the splash screen I was hopeful, however, the little orange dots froze on 3 and just stayed there. Eventually, my laptop shut itself off.
I tried Xubuntu and Lubuntu 14.04 to the same end.
I'm now working with Ubuntu 12.04.5 64bit and it's working well but obviously LTS is running out in a few months so I'd like to upgrade.
My system specs are as follows:
Asus X553M laptop 64 bit, Intel Celeron N2840 @ 2.16ghz, 2 500Gb hard drives, one of which hosts Windows 10, Intel HD Graphics (it doesn't specify which version), 8 gigs of RAM.
Unfortunately UEFI but I have secure boot and fast start up turned off and Launch CSM enabled.
I've used Win32diskimager, rufus and UUI to make the live USB.
Windows 10 runs smoothly so I can't understand why Ubuntu won't.
