[ubuntu] Installed ubuntu but caot boot

Hello everyone,

I installed ubuntu alongside windows 8.1 on my Toshiba Satellite Z-30A. Afterwards, the computer simply booted straight into windows. I booted from my USB with ubuntu on it and decided to install ubuntu over windows, removing windows completely.

Now, I can't boot at all without the USB, however when I go to reinstall ubuntu from the USB it tells me it is already installed (presents the option to install Ubuntu 16.04 alongside Ubuntu 16.04).

I've tried the recommended boot repair option and tried reinstalling a few times and I've also tried a few other settings in boot repair as per some old forum posts on this website with no luck. I also tued secureboot off.

I would greatly appreciate some assistance in getting this working, I just want ubuntu instead of windows now on this laptop.

Here is a pastebin of my bootrepair log as of right now http://pastebin.com/R2JXJ4DH

Thank you
