Greetings, I am working on a project to install Vista 64 Ultimate and Vista 32 Home Premium on a multi disk system. The computer includes EVGA nForce 680i SLI mother board with Nvidia RAID controllers, one hard disk array with 2 SATA drives striped in RAID 0, and two disks that are set up as spanned single disk arrays. The system came from Velocity Micro with Vista 32 installed on one of the spanned single disk arrays. I made a mirror image of that install, Hid that partition with Disk Director and installed Vista 64 on another primary active partition. I installed and uninstalled OS Selector several times and got to a point where I could not uninstall the OS selector. After removing all partitions from several disks and deleting some files I could finally uninstall OS selector. At this point I can use Disk Director to Hide Vista 64, Unhide Vista 32, and make Visa 32 partition active and boot to Vista 32. I can also Hide Vista 32, Unhide Vista 64, and make Vista 64 partition active and boot Vista 64. OS Selector comes up with Boot from Floppy and Boot Windows Vista (English). When I choose Vista, it boots to Vista 64. Tried to find the operating system on the Vista 32 partition but the Selector will not find it. It comes up with the suggestion of changing file names but I have no idea of which files or what names to give them. I could use some help here on how to do this. Not sure what to do now. My mirror images of the operating system partitions may have some scrambled OS Selector files on them. If I knew where to find them and how to recognize them, I could remove them and try to start over. ---------------------------------------------------------- A second issue is where to place the operating systems and page files. All the disks have the same RPM but the two disk in RAID 0 array should have the fastest response. I would like to place the operating system and page file on separate disks but should the operating system or page file be on the fastest drive/array?
