I have a SATA with 320gb running Windows 8 I am trying to dual boot.

I tried Installing It through a USB but received this message. Executing 'grub-install /dev/sda2' failed. I tried using the original sda but I can't add to it. I have 82Gb ready for Ubuntu but every attempt to install it has failed. I have also tried installing it with the windows installer on the Ubuntu website but nothing works.Here is what the partitions look like,

Any help would be appreciated if im being vague ask and I will try to answer.

You should install grub to the MBR. So just let Ubuntu install grub automatically to /dev/sda. You do not want it installed to /dev/sda1 or /dev/sda2. There is no need to add anything to the original /dev/sda, as you said you tried to do.

MBR please explain? I am pretty noobish I did a USB install just automatically but that didn't work either. – Alpha Dec 8 '12 at 8:37
