So.. hello, everyone.

I have a Lenovo G580 laptop, with 4 GB RAM, Intel Core i3, 2.5GHz and pre-installed Windows 8, which I updated to Windows 8.1 .

I was like "wow, it's be so nice to have Ubuntu on it, aswell", since I'm planning on going to an IT college and I heard it's easier to use for Perl and Python programming. (Yeah, I'm young...) So, getting back to the subject..

I want to install Ubuntu 14.04 on the same machine with a Windows 8.1 . I downloaded the desktop Ubuntu 14.04 ISO and "installed" it on a USB 16GB Flash Drive, trying to boot from it, with 'YUMI – Your Universal Multiboot Installer'. I left 90GB of unpartitioned disk space.

I disabled Secure Boot without disabling UEFI, then I plugged in the Flash Drive and chose the option so the laptop would boot from EFI Drive (which seemed the right one). Here's where the problems start appearing.

If I don't press anything, I only leave the Flash Drive plugged in and I turn on or restart the laptop, it gets stuck at the black loading screen, with the white Lenovo logo. With no real reason.

If I boot from USB Flash Drive with enabled UEFI, the laptop restarts all by itself when it reaches the same black loading screen. Again, and again, and again... until I turn the laptop off manually.

If I boot from USB Flash Drive with enabled Legacy mode, the laptop gets stuck (again) at the same black loading screen with the Lenovo logo.

I've googled this all day, but it seems there's no topic / tutorial about this problem. (Or I haven't found it? I don't know.)

I'd need some help, since I really want to have Ubuntu installed here.

This question was marked as an exact duplicate of an existing question.

I don't think it's a duplicate. Apparently, my computer doesn't even enter the boot mode, it just freezes at a certain point. It doesn't even show any error messages.. – Chris Lem' Jun 27 '14 at 20:12
I've been known to be wrong! – Charles Green Jun 27 '14 at 20:16

I always find it most reliable to use a dvd or cd, your computer doesn't seem to be recognizing the flash drive as a boot volume. Try burning a cd instead.
