I am trying to remove OSS Selector without destroying my ability to dual boot Windows XP Pro and Windows XP Pro 64 Bit. I am using the upgrade of Disk Director 10 that is supposed to have 64 bit support. After building a new computer (described recently in Extreme Tech in an article called "Best Bang for the Buck") I had multiple problems installing Linux and have found it impossible to install new operating systems with Acronis Disk Director because DD does not seem to detect my DVD Drives. This is a PC with two SATA drives and two IDE DVD drives. I successfully installed a dual-boot system with XP 32 and 64 bit. My difficulties with Linux related to the fact that, after the Linux install disks booted, there was an error message that indicated that the program could not find the DVD drive from which it booted! I finally solved this problem by booting the Linux distros from an external USB DVD drive, and had to do this with several distros - Ubuntu, Fedora Core, Suse, and Xandros - until finding a distro that worked. Problem #1: Uninstalling previous Linux distros would not get rid of traces of them, presumably their boot loaders. Even when I used an XP disk to fixmbr and fixboot, when Acronis OSS was reinstalled, it still detected Linux distros, usually one new Linux distro every time OSS restarted, along with one "unknown operating system". Clicking on the resulting penguin icons would give an error message related to a problem with GRUB. This problem persisted even after doing fixmbr, fixboot, completely reformatting and repartitioning the SATA hard drive, and reinstalling XP and XP 64 bit. Problem #2: Uninstalling Acronis OSS from within Windows results in only the XP 64 bit Windows bootable, and even reinstalling OSS will not detect the XP 32 bit install. NTDLR is missing, and I can't find it. How do I completely get rid of OSS as well as all of the stray GRUBS and LILOS on my hard drive that persist even after fixmbr, fixboot and a complete format? Thanks.
