Hi, I'm a complete beginner when it comes to multiple boot systems, so forgive me if I'm asking an obvious question. I currently have two hard drives - the first has an installation of XP in a single partition. The second (slave) drive has four partitions, the first of which also has XP installed. OS Selector detects both copies of XP, and allows me to boot from either - so far so good. I then used Disk Director to copy the XP partition on the slave drive to the second partition, so I now have two copies of XP on the slave. But OS Selector does not detect the new copy of XP. I copied the partition as Primary, not Logical - so what am I missing? Thanks for any help.
