I have a sad news guys

Had to remove Fedora 9 and reinstall Windows XP.
Reason - My sis needed Xp when I could not be present at home. She knows nothing about Linux.
I am not going to let this incident dampen my mission to be a pro. Now I am thinking of getting a new HDD(Preferably 320GB) as my current one(40GB) makes it quite difficult to keep both Linux & Windows. Till then the mission is on a hold.
Have any other suggestion guys?
