Let me start from the beginning. My Windows 7 failed. So I thought it would be good time to install Ubuntu. I created a bootable USB drive to make thing easy because the boot sector on my computer is where the problem had originally occurred.
I tried getting 13.10 but it was freezing when I would get to the Installation screen. My next thought was to try an earlier version. So now I have a bootable USB drive with 12.04 on it.
Now, when I get to the Install screen, it does not detect the hard drive at all. I am running a Toshiba Satellite L505D. The error message I am receiving is :
No root file system is defined. Please correct this from the partitioning menu.
The problem is, there is nothing to select it from. I am unable to create a new partition, add, change, delete or revert because there is nothing to select in the above menu.
What should I do?
