    Now a new problem arose, now Windows XP isn't detected, so it's only one OS or the other, i thought the Windows 7 OS disc would rebuild the boot file but would intelligently recognize Windows XP as an OS and include bootmgr in the startup process so that i could truly dual boot, but it hasn't. With Windows XP repair, i can use the recovery console and use the "fixboot" comand which rebuilds all boot directories so that the OS is detected, but with Windows 7 repair i cannot use manual recovery console to do this. My problem before was that i installed Windows XP on a separate partition and Windows 7 and XP were not presented as options upon startup, it was just XP, so i used my Windows 7 disc to repair the boot configuration.

    How do i get both OS'es to be recognized as OS'es by one another? I installed Windows 7 on a separate partition in my ThinkPad T43 and i could choose to boot either one no problem upon startup, how do i fix this so i can truly dual boot? I heard you should install XP first then Windows 7, but i'm not in the mood to back everything i have up.

    I don't know what step you're on, but the general process goes like this:

    1. Install older OS.
    2. Install newer OS.
    3. Edit the boot record either manually or using a program like EasyBCD to recognize both OSes.

    It's located on the system partition. \boot\bcd

    It's a binary file, so use BCDedit or easyBCD to edit it.
