This PC came pre-installed with Vista Home Basic. I want to install Windows Media Center on it (not included with Vista Basic). I’ve been reading all kinds of suggestions about dual booting, partitioning etc. but I haven’t seen anything about my particular problem.Vista won’t allow XP to be installed on it because it’s an older version of Windows. I have a second hard drive installed as a slave and it is listed as the D drive. I’ve formatted it but I’m unable to gain access to it to install XP. The C drive cannot be formatted. I’ve attempted partioning it but must have done something incorrect because I couldn’t do the install.Can I disable or do something with the C hard drive to allow access to the other drive? My goal is to run only Windows XP Media Center.
