    Drive letters changed after an optical drive installation


    Hi all

    I have installed an optical drive in my computer today and my drive letters were changed. I have changed them back to what they were and after restarting my computer I was unable to log to Windows 8.1 due to the OS being unable to find user profile (my user profile is moved outside of the system drive).

    I restored my system to the point from before the new drive installation, but I still would like to change the drive letters around, as some of my software relies on specific directory paths with drive letters.

    1. The state from before the installation of the new optical drive.

    System (C:)
    Virtual Box (D:)
    Program Files (E:)
    Passport (F:)
    Storage (G:)
    Program Files 2 (I:)


    2. The state after installation of the new optical drive:

    System (C:)
    Virtual Box (D:)
    Program Files (E:)
    Optical Drive (F:)
    Passport (G:)
    Storage (H:)
    Program Files 2 (I:)


    3. What I'd like to have:

    System (C:)
    Virtual Box (D:)
    Program Files (E:)
    Passport (F:)
    Storage (G:)
    Program Files 2 (I:)
    Optical Drive (any letter, preferably X:)

    My user profile WAS located in G:\Users

    It is now located in H:\Users and I can log in to Windows. After changing the drive letters around to 3. above I can no longer log in, as Windows is unable to find the user profile on H:\Users anymore.

    I use EaseUS Partition Master 10.0 to change the drive letters.

    Is there any way I can change the drive letters and make Windows aware of user profile path change?

    Thanks.

    Are you sure this method will make Windows aware of the user profile relocation?

    You don't want to change the drive letters of any drive that you moved the profiles to. If you do, you will break them.
