    Incorrectly Partitioned Disks after reinstall


    So I had to reinstall my Operating System due to problems I could not solve, and due to the lack of backup.

    I reinstalled Windows 7 to a different drive from my old drive.

    For some reason my C:// drive is not the drive I am using now, and the A:// drive is the one that I currently am using.

    What I want to do:
    - Make the current drive (A) as Drive C.
    - Be able to delete the current Drive C.
    - Use the deleted partition for Data.
    - Be able to boot Drive A - hopefully C:// after.

    Any suggestions?

    You're stuck with it. Far too difficult to change the os registry letter.

    It doesn't matter, it will work fine whatever letter it is.

    If it really worries you, you will need to reinstall either by booting the dvd, or by applying image from the wim.

    Is there any way to remove the old installation at all?

    I dislike having to choose which Operating System to use at boot.
    I'd like to be able to use the other drive for backup and data.

    If you are desperate for your new install to be C:

    Boot the 7 install media , format the C and A partitions. Mark whichever you are going to install onto Active. Mark any others Inactive.

    OR

    If you don't mind keeping the one you have as A :

    Open elev cmd ,

    bcdboot a:\windows /s a:

    diskpart
    sel vol c
    inact
    sel vol a
    act
    exi

    Close cmd prompt.

    reboot

    Always unplug all other HD's during Clean Reinstall.

    And always boot the installer as running it from the old OS blocks the C drive letter from use for the new install. How to Boot your Computer from a Bootable CD or DVD

    I am currently using Drive C, the only thing I need to do is make it System/Active I believe?

    Thanks, exactly what I wanted. I would give some reputation but I need to spread some around.

    Are System Active Boot flags on C now?

    Reboot and tap the F8 key to see if Repair My Computer is still on Advanced Boot Options.
    If not and you want it run Startup Repair - Run up to 3 Separate Times which is preferred for moving the System flag for this reason.
