Okay SOOoo is OS Selector wisely enuff (as-is) software to do this type of XP dual boot task? I boot to the OSS (it load up with errors, I also had to tell it to ignore all or I won't be able to get to the menus selections) and then select the 2nd active HD to install another copy of XP pro sp2. The first phase had finish copying all xp pro files and requested that it need to reboot but then the OSS had been deactivated when it reboot back to the DOS shell and the XP installation has stopped w/all errors. What the?,... i'm only using E-IDE drives there is no raid setup, there no SATA setup. Why also that i'm not able to make a copy of my mbr to a cd-r/dvd-r nor can I hide my first xp os boot or place a bootable strap in place for my secondary xp pro os to install.
