You misunderstood me, I am sorry. I was not clear enough. I am not going to
use Windows until I have children. Dual boot with Mandriva and Ubuntu is good
enough for me, even too good.
Then I will buy another computer and install Windows XP on it.
It is useless to have XP and Linux on the same hard disk, because Windows
collapses first and then you have to reinstall Windows and then reinstall
Ubuntu, otherwise only Windows boots. The GRUB is wonderful, it respects the
small children (Windows).
Again, please, do not misunderstand me, Windows is great for certain purposes,
but it is by no means suitable for me.
