Please guide me on how to recover mails from evolution 3.2..Due to my experiment with Ubuntu i am unable to boot and Ubuntu freezes when booting up.But i am able to login to terminal mode using ctrl f1 .So please guide me on how to accomplish the same using a live cd or any other method.

The reason to reach such a stage while boot up is that i played with grub menu tutorial from google.I also tried to repair the boot by usng boot-repair program.But still ubuntu freezes while booting.
