Ubuntu Installation :: Change Order Of Boot Menu?

Using StartupManager (as Quackers had suggested) I do indeed have Windows as my default boot, although it appears at the bottom of the menu. See Dilemma 1 below for that detail.

Dilemma 1:Grub2 has set up the boot menu so that Windows is the last item on the menu. This is because the Menuitem entries for the Ubuntu kernels are generated by script 10_linux, while the Windows Menuitem entry is generated by script 30_os-prober. Of course, in generating /boot/grub/grub.cfg, the 10_linux script is executed before 30_os-prober, dictating the order of their appearance on the menu.

I'd like to see Windows as the top menu item. Under grub, I would edit /boot/grub/menu.lst, pull the Windows menu item out of the "Automagical" section and voila! It stays on top no matter how many times I upgrade the kernel. While I could possibly do the same with /boot/grub/grub.cfg (see thread "how can I change the order of the boot menu?" for the suggestion) we should all know by now that the next time I update the kernel, my changes will all go away, because we are not supposed to edit that file by hand.

Dilemma 2: As I download and install kernel updates, all the old kernels still show up on my boot menu. My concern is that eventually the sheer number of Linux kernels will render the boot menu unreadable. This is especially of concern if I cannot get Windows to the top of the boot menu. Under grub, I used to edit the menu.lst and comment out the listing of any kernels more than 2 versions old. Now, how do I arrange this omission? A manual edit of 10_linux will be acceptable, provided it still displays the 2 or 3 most recent Linux kernels and their corresponding memtests.
