After using ADDS to separate my HD, and installing a new OS on that partition, Acronis OS Selector boots off the newly installed OS, no matter which one I choose in the selection screen. If I disable Acronis OS selector, the Windows OS selection screen comes up for maybe a second, and if I'm not quick, goes to the new OS. Also, when I (am quick) boot off the original OE, the drive letters are correct. When I boot off the new OS, the drive letters are all changed around? Orig. OEM OS is Win XP MCE, new OS is WIN XP Pro x64. Thanks for any help!!
