    Change drive letter


    When I installed windows 8, I did so by creating a second partition (E) and I kept Vista on my C partition.
    Right now I want to remove Vista and merge the two partitions again (which I know how to do).
    My question is, can I safely name that merged partition C? Or will this mess up my windows 8 install and do I have to keep it E?

    Not clear what you mean.

    When you boot into win8 - does it identify itself as E ?

    If so, then you can't chage that successfully without a reinstall.

    I have Vista installed on C, WIndows 8 on E and my documents are on D. I want to remove Vista and merge C and E into one partition, hopefully naming that partition C but if I understand you correctly that is impossible?

    That still doesn't help.

    What is important is the o/s system drive letter.

    That is the letter it calls itself when you are booted into it.

    The letters you see from Vista may be different from the letters you see from Win8.

    For example, I am booted into win7x64 now - It calls itself D.

    That I cannot change without all sorts of major problems.

    SIW2 is right.

    Boot with Win8 and see what it's partition is called. Normally it's C (on a simple setup of 2 or 3 hdd's) and Vista gets another letter then.

    Merge the partitions from Win8 if you want to keep it.

    And of course that current letter is not important: If C is a letter that's not used (by any drive), you can pick it again later, after doing the fusion.

    How odd. Never considered the fact that drive letters were depended on the installation. Anyway, with me all drive letters were the same regardless of which OS I had loaded. But in the end this question is moot now since I just did a reinstall. Thanks for the help anyway.

    EDIT: Ah, I see now. No I did an install from WITHIN the old OS, so the drive letters could not have changed. I suspect that can happen though when you do an install from outside the OS (during aboot from the install dvd)?

    Yep.
    That last part happened here: drive letters were independent after DVD/USB clean installation.

    Glad you fixed it.

    Lpent,

    why is it so important for you to have drive letter C?

    Why don't you just remove partition C: and take it from there?

    Keep the system reserved partition.
