Dual Boot with windows: where to put the boot loader?

Hi all,

Thanks everybody for the good advice. I installed grub into the MBR and 
everything worked fine. However, I had to choose ext3 over xfs otherwise 
it only wanted to install lilo. And sorry for Lilo fans but I really 
cant stand this loader. So does anyone know why the ubuntu installer 
doesn't give you the option to install grub in the mbr if you choose 
xfs? You can choose grub but then it warns you if you install it on an 
xfs disk, you might get in trouble. Ok, but no option to install in the 
mbr. It defaulted to lilo. When I saw this, I turned off the computer, 
installed again and chose ext3 instead :)

So now ubuntu is installed on my dad's computer, but he cannot use it 
yet because X wouldn't come up. He has a no-name computer with a nice 
Philips monitor. What kind of info do you need here so that I can debug 
this problem?
