Hello,

Recently after I added another hard drive to my computer - my ubuntu 12.04 can't get pass the purple screen during the start up logo. I tried to disable/removing the added hard drive. I also tried doing the nomodeset by editing the grub file. Any ideas how to fix it? Thanks in advance.

If you hit the Esc key after it's past the grub menu, the splash screen goes away and you can see line by line where it's at in the boot process. Where is it stopping at when you do that?

Does it respond to Ctrl+Alt+F1 ? if yes you can get to logs to see the issue in /var/log or in /home/user/.xsession-errors
