    Okay so i changed my external hard drive into an internal hard drive(2nd hd).
    My first hard drive had windows xp on it.
    I plugged in my second hard drive and installed windows 7 on it.
    Both hard drives were plugged in during the installation.

    Everything worked perfectly!

    However when i unplug my 1st hard drive, i can not access windows 7 on my 2nd hd.

    When i boot i get to the OS selection screen and when i choose windows 7 i get.
    (0xc000000e The boot selection failed because a required device is inaccessible)

    When i plug my first hard drive back in, it works.

    How can i access windows 7 without having the first hard drive plugged in?

    It will take a little work and you will need the windows 7 and XP disk.
    I assume you still want to boot XP later.
    If you are using IDE drives,remember to change jumpers according to
    the way the drives are connected.

    Disconnect the XP drive.
    Boot to the windows 7 disk.
    During the first few steps,look for a link that says repair options.
    Click that and run startup repair.
    After it is done.reboot and windows 7 should start.
    If not,run startup repair until it reports no problems.

    Once you have the windows 7 drive booting again,shut down
    and disconnect it.
    Connect the XP drive and boot to the XP CD.
    Select R to go to repair console.
    At the repair console type fixmbr and hit enter.
    Reboot and see if XP starts.

    If both drives are now booting indepedently,shut down
    and reconnect both drives.
    Set the first boot device to the windows 7 drive and start
    windows 7.

    At this point.if you don't want a bootloader,you can
    just change the first boot device in the BIOS to
    change the boot drive as both drives now have their
    own MBR.

    If you want a bootloader,do this....
    Download this and run it on windows 7.
    Use it to add XP to the windows 7 boot menu.

    Welcome to TSG :)
    As far as Leroy goes, I agree, its about the easiest way.
    The reason its doing this (out fo interest I guess) is that the little bit that tells it where to look for where Windows is is on the drive where your first OS was installed. If thats gone, theres no little bit telling it where to look, thus it doesnt work.
    Think of it as having boxes with the numbers 1-10 on, and different stuff in each one. On the front of the first box is the list of where everything is. As long as the first box is there, all is good, if its taken away, you cant find a thing. same thing :)

    Disconnect the XP drive & boot to the windows 7 disk.
    It will work.

    Best of luck!!

    That was your problem .. I only connect one drive at a time when installing a system.

    Depending on the manufacturer of your system .. You may not need to install a boot loader.
    In a HP .. just tap the escape key during the bootup .. and you will enter a boot loader where you can choose which HDD to boot from.
    In a Dell .. I think it's the F12 key
