My computer boots to a black screen, what options do I have to fix it?

I have installed Ubuntu 12.04 (64bit) on a new Windows 8 Sony laptop that I have bought recently.

When I attempt to boot Ubuntu all that appears is a black screen with a single coloured line across the top. Could this be the result of some incompatibility with the system graphics card, AMD Radeon HD 7650M 1GB?

How do I solve this?

Thanks you for any help.

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

Try to boot your system using nomodeset parameter. You can set this parameter when grub loads press E button. Look for the line that starts as

linux /boot 

and add in the end of the line word nomodeset. So it should look like this

linux /boot ********* quite splash nomodeset

After that press CRTL+ x and see if you can boot now. If it successful I recommend you try to install FGRLX frivers for your card. You can find HOW-TO here
