Heh, there is some difficulties I encountered when trying to install windows on one of my Ubuntu partition. Why I want Windows on my laptop? Well - I had to install Windows due to my brother-in-law request to play games with me.
Well I've tried to use cedega to play games with him, but I failed to install the game because we dont have the CDs, the only way to play the game is by copying the source directly from my brother-in-law laptop to mine.
Virtualization? Nope, this one could run windows on my Ubuntu but it cannot play any games because you will experiencing a very laggy system cause by non supported graphic card on virtualbox. Plus - my RAM is not enough to run it.
So I installed Windows on one of my Ubuntu's partiton which I named it "/share" (mostly all my trash files is here) and successfully run Windows after 30-40mins of installation process. Unfortunately, during the partitioning process I do make a noob mistake where I did delete my swap partition :-P (Lame huh)
I repair my grub and everything went well except my system is not as good as before, and I do have some problem with memory management cause I have no swap on the system. Can I make a swap ? Yes I can.. But I am thinking of a Hardy Heron fresh install to replace the old Feisty -> Gutsy -> Hardy System (i'm on my way to burn the hardy CD's on my CD-RW right now).
