Two operating systems

[alyoob]

Is it possible to have Windows xp home installed and windows xp professional also installed on the same computer. If so can I install windows xp professionals without losing any data in my windows xp home operating system.

I see why not.  I've installed Vista on one drive partition and XP on another.  Once you've partitioned the disks it should be pretty easy.  See Vista/XP Dual Booting procedures and my last post.

Not as long as you install XP Pro on a different partition.

alyoob,
What exactly are you wanting to accomplish here ? ?
Without specifics it's hard to advise.
All the things you stated can be done....the "why" determines which would be the best choice...
