Grub.?

> /grub/boot/menu.lst but I cannot find a way to do that - in fact, I can't

Needs to be /boot/grub/menu.lst

Try editing with gedit. (need to be superuser)

sudo gedit /boot/grub/menu.lst

Then change the timeout line from 10 to say 600, this number is in seconds
that grub will wait before booting the default OS, You could also change
the default line to your choice for the default operating system to boot.
0 would be the first OS in your list, then count up from there.

example:

timeout    600

default     1
