    I wish to install vista 64 on my computer that has Windows XP Pro as dual boot.

    Drive C would have XP Pro
    Drive G Vista 64.
    But when you boot vista it calls changes drive G and calls it drive C.
    Can this be stopped or can I install windows XP and Vista 64 to the same
    drive?

  2. That is the normal procedure. When you are using XP the drive is C: when you
    use Vista the drive is C: The other problem, of course, with dual booting XP
    and Vista is that, whenever you boot to XP, all of your system restore and
    shadow copy points in Vista are deleted. This is a known problem that is not
    going to be rectified.

    Personally, I run XP on virtual machine software (VMware workstation,
    although this software can be expensive.) Alternatively give Microsoft's VPC
    2007 virtual software a try (still free as far as I know). there are
    limitations to virtual machines but if you just simply need XP for the odd
    application that won't run on Vista then virtual machine software is an easy
    option. Providing you have enough memory on you system you can also run the
    two operating systems at the same time.

    Since you can't install the 64-bit system from your XP Desktop you cannot
    get your drive letter to change. John's advice provides good advice and
    alternatives.

    Actually, there is a way to dual boot Vista x64 and XP x32 and retain
    same drive letters both under XP and Vista.

    Here is how:
    Under XP change the drive letter of your DVD-ROM to something other
    than the drive letter you want to have your Vista installed.

    Boot from Vista DVD, click "Install Now" and hit Shift+F10, start
    diskpart and make any partition changes you need (I personally shrunk XP
    partition by 32Gb and then created another partition for Vista and
    assigned it drive letter D: )
    Go through Vista install as you normally would (make sure that
    "Automatically activate when connected to internet" is unchecked so you
    don't have to activate Vista twice -- you'll see the reason for that
    later). Also don't install any updates or non-disk-essential drivers
    just yet.
    Once you log in to Vista for the first time -- open to registry editor
    and go to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. Then rename
    \DosDevices\D: to something else for now (presumable this is your XP
    partition), rename \DosDevices\C: to
    \DosDevices\[DESIRED_VISTA_DRIVE_LETTER]: (where
    [DESIRED_VISTA_DRIVE_LETTER] should be replaced with the desired drive
    letter for Vista partition -- D in my case). Now rename previously
    renamed \DosDevices\D: to \DosDevices\C:
    (see 'How to restore the system/boot drive letter in Windows'
    (http://support.microsoft.com/?kbid=223188))

    Close regedit and reboot. Now if you boot into Vista you will not be
    able to run anything and your profile will not be loaded -- so instead
    of booting normally choose Safe Mode with Command Prompt (by pressing F8
    on boot menu screen while Vista option is highlighted). Once you boot
    into Vista Safe Mode with Command Prompt change drive to your DVD drive
    and start Vista setup AGAIN by typing setup in command prompt.

    Go through Vista installation again and enjoy same drive letter
    assignments under XP and Vista
