I made a bootable USB for installing Ubuntu 12.04 LTS alongside Windows 8.1. I inserted my USB device and then booted into it. Then it showed me 2 options - 'Try Ubuntu' or 'Install Ubuntu'. Now I press 'Try Ubuntu' and then it says, "The system is running in low graphics mode". Then I press 'OK'. Then it showed me 4 options. Then again I click 'OK'. Then it shows a black screen and nothing happens.

I have tried all possible answers provided in AU. What should I do? Please help.

PS :- I am using Windows 8.1 with dedicated graphic card which is AMD Radeon HD 8670M. I am trying to do this in a Dell Laptop 3537 Inspiron.

UPDATE :- I tried running the liveUSB session with nomodeset on and i was able to enter the installer. But when I run boot-repair(so that my Ubuntu gets detected in the GRUB menu) after installing Ubuntu successfully alongside Windows 8(following this tutorial with nomodeset on, I get the following error:-

your system is running in legacy mode
boot repair done
