I have recently switched from Windows 7 to Ubuntu 12.10. I have installed Ubuntu 12.10 and I cleared everything from my computer, but it randomly stops at different screens.
- Only a purple screen comes up.
- I can choose Ubuntu from a list and a blinking white dot appears in the top left corner.
- The previous things happen and the Ubuntu login screen appears an I can log in.
It is random. and I have not changed anything. I can always insert the bootable CD and it will work every time.
