I am trying to set up a dual-boot between this an my original Windows 98 SE setup that resides on a different drive." i'm going to just try to point you in what i think is the right direction on this. i do not have all the answers, and i may be wrong. to the best of my knowledge, you can have only one physical drive from which operating systems can boot, and it or they (if you multi-boot) must boot from this primary disk. i think that is your problem... the fact that your os's reside on two separate physical drives. you can create multiple partitions on one physical drive and multi-boot that way, but not the way you are attempting. that said, let's say you make the win98se drive your primary, or bootable drive. i think that you can then put a few of the winxp files on that primary drive and store the rest of the os on a separate logical partition, and still boot it. another thing to consider (and again, i am not by any means the last word on this stuff), is the order in which the operating systems are installed. the sequence has to be the older os's first. i have provided a ms link at the end of this post that addresses this more. there are ways around the physical drive limitations i have alluded to above. i believe that powerquest's BootMagic (that comes bundled with PartitionMagic) will help you accomplish what you are trying to do. from the powerquest support site:"BootMagic supports booting most operating systems from second, third, or fourth disks and beyond. Some operating systems, such as OS/2, Linux, and BeOS, are designed to boot from any disk. Others, such as Windows 95/98, Windows NT, and DOS do not commonly support booting from a non-primary disk." powerquest.com i currently dual boot win2000pro and win98se. both os's reside on separate partitions i created (using partitionmagic) on the same physical drive. i have a second physical drive installed, but i just store full system images on it, and do not boot from it. in case you have not read it, here is a helpful ms kb article titledHow to Multiple Boot Windows XP, Windows 2000, Windows NT, Windows 95, Windows 98, Windows Me, and MS-DOS (Q217210) support.microsoft.com hope some of this helps :) mark
