It be itching to see your screen full of 6 -10 lines, but in your system you might have installed only one or two OS,
so if ur running ubuntu in your system, here is an easy way to edit the grub menu.
Open terminal type “sudo gedit /boot/grub/menu.lst”
then a new window will come in that go to the bottom of that page and there you can see name of the OS and u can remove the unwanted recovery mode, and u can set different name to your OS like My ubuntu etc..
Try out and checkout the difference.
