I previously installed Ubuntu 12.10 using Wubi but it heated up my laptop too much and my battery ran out in minutes, so I removed it.
Now I am trying to do a normal dual-boot install using 12.04, but it wont go further than the boot screen. I am booting from a USB and when I reach the boot menu it gives a beeping sound. When I click "Install ubuntu" or any other option there is another beeping sound, but the process doesn't go any further.
My specs: Dell Vostro 3450 , Intel core i5 2410M, 4 GB RAM with AMD Graphics and Win7 64 bit professional pre-installed.
