|that will not get you anywhere, because the GRUB boot loader installs itself BEFORE windows XP (thanks be to jesus for the small mercies :-)|
boot into ubuntu and do the following:
Copy these two lines into the terminal and press enter.
1. 'sudo cp /boot/grub/menu.lst /boot/grub/menu.lst_backup'
2. 'gksudo gedit /boot/grub/menu.lst'
Find this line in the document that was just opened
... default 0 ...
Replace the 0 with the number on the startup list corresponding to the option you want, counting from 0. For example, if you have a list like this one and want to change to Windows XP Home:
Ubuntu Kernel 18.104.22.168
Windows XP Home
... you would change the number to 3.
