twin boot Inspiron 1520

[norman]

I am buying an Inspiron 1520 with Ubuntu 7.10 installed and I want to
set it up with Win XP Pro and Ubuntu 8.04. I thought I would do this by
first installing XP Pro, which I presume will remove the Ubuntu 7.10 and
then to install Ubuntu 8.04 full version and not the upgrade.

Could some kind person please let me know if what I propose is the best
way to set up the twin boot condition.
