I had a Linux Mint 9 and Windows 7 dual boot machine that was working fine until Mint was auto updated. Now it won't boot up, live CD's get to the splash screen menu but won't proceed any further. Sometimes the machine hangs and gives long lines of text errors in the form of
xxx.xxxxx i/o error sda 5 and etc.
What really confuses me is that the live CD's won't work and I cannot do a clean re-install either using Ubuntu, Mint or Windows 7.
What might be causing this and how can I correct it?
