When I try to install on the partition, it loads the Window's XP files and then a blue screen comes up, saying that Windows has shut itself down to prevent damage. Check for viruses, uninstall recent programs, etc. to fix the problem.
Not sure why it does this; I have 50GB formatted and sitting there for XP, but it won't let me install the operating system. Can you have XP & 7 on one computer?
