Thanks much lurkswithin. I think I understand what you're saying now. Only problem is that now something is wrong with my Complete System Backup program in Vista. I tried over and over the last 2 days to create a new Complete System Backup onto one of my hard drives, and it gets maybe 3/4 of the way done and then blue-screens every time. The blue-screen says "DRIVER_IRQ_NOT_LESS_OR_EQUAL" and also mentions nvstor64.sys. I'm debating on whether to maybe do a repair install of Vista before attempting another Complete System Backup, and then doing your plan. I could also wipe the XP D: partition, recreate it and install Visa on it, and then use that Vista's Complete System Backup program to backup the old Vista drive. Only, the old Vista drive is a logical drive in an extended partition. Hmmmmm......
