I've been pulling my hair out the past couple of days trying to access my installed Ubuntu.
Here is what happened: I wanted to create a dual boot of windows 8 and Ubuntu 14.04. So I downloaded an Ubuntu Distro onto a usb drive, and installed it from said usb drive.
Everything was fine. Ubuntu was working flawlessly.
A couple of hours later, I went to shut down my pc. When I clicked on the shutdown button in Ubuntu, the computer froze. I was able to move the mouse around, but I couldn't select anything. I ended up having to just hold the power button in till the pc shut off.
I then went to power on the pc to make sure nothing was adversely effected, and it booted me directly into windows 8.
I found out how to access my windows boot menu, and attempted to go in and boot back into Ubuntu. The problem is, there is no Ubuntu entry in my windows boot menu.
I have went as far as to try booting into "try Ubuntu" from the usb drive and running boot repair. It didn't pop out any errors, so I went back into the windows boot menu expecting there to now be an Ubuntu entry, but there is still none. Then I went into the windows boot menu and turned off secure boot, and reattempted the boot repair, still nothing. So basically now I have Ubuntu installed somewhere on my pc, and I can't figure out how to access it!
I should also mention that this Ubuntu installation was over a preinstalled windows 8.
I'm stuck dead in the water here, and I need to figure this out.
P.s. I am a brand new Ubuntu user, so this is especially confusing to me.
