You can run "sudo gedit /boot/grub/menu.lst" on terminal and edit the entries... But the thing is, when I updated Ubuntu from version 7 to 8, it added a couple more entries before the Windows entry and I had to go and change the default value... And this repeated during another update session...
Also, earlier when I used Red Hat Linux about 6-7 years ago (college years), I remember there was a graphical interface in the control center where it was easy to set grub options... Anybody know where I can get something like that?
