Now if I could only figure out how to configure GRUB to boot to choices instaed of to any key for menu with Other being the default, I'd be all set
What you have to do is edit the file /boot/grub/menu.lst
This can only be done as root and you should be very careful because hosing this file badly can cause a boot failure. For good measure, you should probably copy it before making any changes so that if something goes wrong you can recover it. Something like "cp -p menu.lst menu.list.first"
Then edit the file with your favorite Linux editor. Near the top should be a line that says default=0. This means that the first choice on the list will be the default. Change it to default=1 to have the second option be the default, or default=2 for the third and etc.
Then change the actual lines of the file, NOT the commented ones beginning and ending with ###. Change "other" or any other entry to whatever you want. Save and when you reboot, you should have a modified menu.
