Do I partion the drive to have windows on one partition other programmes on another and all data files on another? If you wish yes!
Is that the best way.Is the idea of this is that if i need to reinstall windows i can do so without messing everything else up? Yes, you can reinstall windows to the Windows partition without affecting your files. But make a regsitry backup too and save to a different partition and reload it so all your programs work again. You may even need to reinstall some.
Also do I need to buy a programme to do this or do I get this option when installing windows?
Partition magic is my favourate software for partitioning, it allows many features. Great software! Maybe other can suggest better, or even free ones.
apologies for a long question. No need to apologise, we are here to help.
Just ask if you need more help,
