GRUB 2 boot order dilemma.

[Frozencurrent]

I'm very new to Linux but when I first installed it, I downloaded the Start-Up Manager so I could change the boot order. I have a dual boot Windows-Linux, I set the default as Windows. Recently my computer started booting to the system memory test in the grub menu instead of Windows. When I try to open the Start-Up Manager now it asks me for the password as usual and then does not start.

Would anybody happen to know what the problem may be?
And how I would change it back to windows for the default?

I'm running Ubuntu 9.10.

I have resolved half of my dilemma

I opened a terminal,
typed gksudo gedit vi /etc/default/grub, (Permission was denied when I tried to access /boot/grub/grub.cfg)
edited the boot order on the second window within the gedit,
pressed save,
then typed update-grub

PROBLEM SOLVED!!

Does anybody know why Startup Manager won't start though? My Linux did update software the other day, maybe that has something to do with the dilemma?

if you change the value of the GRUB_DEFAULT variable to a string instead of a number, you won't have to change it every time there's a kernel update:

GRUB_DEFAULT="Microsoft Windows XP Professional (loader) (on /dev/sda1)"
