Sorry in advance if this is an "obvious" question but I sure don't see an exact answer anywhere in the docs or forums... If I want two bootable partitions (one being a copy of the other one) apparently (from posts in this forum) I have to modify the boot.ini file or for some reason OS Selector can't "find" the other partition and its cpy of WinXP. (As an aside, that seems like the job of the Disk Director software; why doesn't IT offer to do this when it copies a partition with WinXP?) Several posts refer to modifying the boot.ini file. One post referred to the Microsoft note that shows "how" to modify the boot.ini file. But can anyone explain "what" the modification to make to the boot.ini file? Like exactly what command? Apparently I have to plug in the name of the OS (can it be any name I choose like "My 2nd Copy of XP"?) AND I have to plug in an ID#. But what is the ID#? It's all greek to me! Thanks!
