my problem is that when i first installed OS selector it found all my operating systems(XP Pro on one hard drive, Vista on a SATA raid 0). Both loaded the Vista dual boot entry, which was on the MBR of the XP drive. So i deleted the Vista and XP entries in the OS selector and restored the MBR for XP and Vista on there own drives(i unpluged the other drive when I did this so Vista wouldn't install the vista dual boot menu). Then i could boot up to either OS by selector their drive in the BIOS as first. OS selector would not find them again after this by the MBR. I tried uninstalling OS selector and reinstalling and that did not help, so I tried uninstalling again after deleting BOOTWIZ folder on the two drives. I still can't find the two operating systems. I tried boot floppy and that loaded vista, so i deleted that in the OS selector and tried to find XP and Vista again, but it still can't find them. I reinstalled XP and then Ubuntu and now OS selector can find them but still not vista. So now I have only XP and Ubuntu(GRUB) as OS's in the OS selector but not vista or "boot floppy". Also when i try to turn off OS selector, no operating systems show, so it wont let me turn OS Selector off.
