I have an HP9340 Media Center/vista. I am trying to create a double boot system with Win XP Pro. I have been unable to load XP. It always stops at the point after files are loaded, just before you make selection as to which drive/partition the system will be loaded. I have removed all drives from the machine, with the exception of the drive that I will use for the xp system. I have tried a drive already formatted to NTFS, as well as the drive having no format at all. Still no luck. I have tried a second XP system install disk, and same results. Prior to all these install attempts, I wanted to see that the dual system would work. I created a second version of vista, via an older image file. This dual boot technique worked fine, utilizing two separate physical drives. Any suggestions as to what is happening here, realizing that when I attempt the XP load, vista and other data drives are out of the machine. I have ran chkdsk on the installed drive. I also have substituted another drive for the Xp and got the same results . This should be simple. This is not the first time for me to load and set up a system by any means. Thanks for any input.
