ubun2

ust installed ubun2 9.10 in asecond partition with xp after shrinking xp partition
goes from boot  linux os  or recovery to no such device with a long string matching the string  its looking for if you hit e and read the command its trying to implement. how do I  boot into ubun2

I recently installed ubuntu on my laptop which already has windows xp on it. Ubuntu got installed successfully and shows the Grub boot loader.
 
Since ubuntu was the latest installed operating system, it always defaults to ubuntu. Since my job requires quite few microsoft products like office, etc., i need to choose the Windows XP operating system in the menu item and it boots correctly. It will be very helpful to change the default boot loader to windows itself so that i don't need to choose it every time. Please suggest, thanks.
