I recently installed Ubuntu 12.10 64 bit version on my Sony Vaio laptop after deciding I didn't want windows 7 home premium anymore.

I originally booted the set up program for Ubuntu by extracting the files in the .iso to a folder in Windows and running the Wubi.exe but I discovered that this only made my computer have a dual boot option when powered on which is not what I wanted.

I then proceeded to install Ubuntu via usb and that seemed to work until I rebooted. Upon reboot the screen went purple as if it was going to load up Ubuntu but instead it just black screened and hung there. I then force shut down the laptop and turned it back on. This time when the system started up I got a menu with the options of Ubuntu and Advanced options for Ubuntu. I chose Ubuntu and the system started just fine but the black screen continued to appear whenever I rebooted.

I tried formatting the hard drive and re-installing Ubuntu that way but the problem persisted. I am at a loss with what to do. I have and AMD ATI Radeon Graphics card which I believe is the cause if the problem but I still don't know how to fix the issue.

How can I fix this ?

If you press ESC during boot (black screen) to see verbose (ugly) output. Maybe you can tell where it's hanging. My only other suggestion would be to try unetbootin vs wubi. –  earthmeLon Feb 26 '13 at 18:59
Pressing escape stops the hanging but it doesn't stop it from happening in the first place. –  Jeremy Novoa Feb 26 '13 at 19:08
The point was that pressing ESC when you see the pretty Ubuntu splash would give you additional information, such as the program/module causing the problem. –  earthmeLon Feb 26 '13 at 19:09
Oh I apologize I misunderstood. Anyway the first issue I see is that it cant open dev/mapper/ubuntu-root No such file. The second is that one of the objects that loads says FAIL in red letters on the right side of the screen. –  Jeremy Novoa Feb 26 '13 at 19:17
Im trying to identify what is failing to load but it goes by too quickly for me to identify –  Jeremy Novoa Feb 26 '13 at 19:20
