I have an older Dell xps 400 running XP.I was just wondering if someone could explain how the hard drive needs to be partitioned.I know that from the factory it has two partitions a very small partition and the large partition that the os is installed on.I need to know how big to make the smaller partition.I was working on the pc and and it gave me the blue screen and now it wont start back up.It loads to the windows splash screen but will never finish loading.I am going to erase the whole hard drive and reinstall everything from scratch.Thanks
