I have recently installed windows XP onto my computer but Windows 2000 still remains and everytime I start up it makes me choose either operating system, plus it takes up too much space! How can I remove it??
Do you have the means of backing up your files on XP? When you installed XP you would've had the option to delete the 2000 installation, instead it has partitioned your hard drive and given you a multi boot option.
I suppose the easiest way for you would be to format your PC and do a fresh install of XP on the entire hard disc.
