After installing the gui for grubit appeared in the Applications/System tools,
section. Grub wouldnt work however it says on the icon "choose next default for
grub" bu nothing happens when i click on the icon, so what gives, this is the
third error from the Ubuntu menu system. these instructions for installing grub
didnt work for me, i have installed Linux Ubuntu 64 onto another partition, but
during its installatin it didnt ammend the Grub so that i could choose betwen
32/64 and XP, what can I do besides whats in the video?

I tried to reinstal the Grub both from 32bit Ubuntu and the 64bit live CD.
