    Unable to install Windows due to 2 serperate volumes being marked as C


    Let me give you some background:

    I have two 1 TB internal hard disks.

    On Disk 0 there is nothing but data, but on Disk 1 my Windows OS use to reside, until a horrible malware attack removed all my program files and Windows folders. I had no disk backup.

    This is the layout of my 2 disks:

    Disk 0 :
    • One large data partition. No OS.

    Disk 1:
    • 1 Partition for Windows 10 in UEFI mode
      1 partition for data
      1 partition for data.
    The partition that housed the OS was the one effected.

    Now all I want to do is just install Windows back to my system partition. Without performing a clean on my HDD.

    I have tried everything like copying the installation media contents of a separate 9 GB partition and then starting the installation.

    I keep getting the following error:


    Unable to install Windows due to 2 serperate volumes being marked as C [​IMG]


    Can someone explain to me how on earth can there be 2 mount points with the same name as C ?

    This is causing problems like :


    Unable to install Windows due to 2 serperate volumes being marked as C [​IMG]



    Unable to install Windows due to 2 serperate volumes being marked as C [​IMG]


    This is what I believe the root of the problem is. Please note that I had to create my USB Installation media from Linux, as I don't have a CD Drive or another Windows machine.

    Why is the Microsoft installer so buggy ?

    How can I just install Windows without removing other partitions ?

    :)

    C windows installer folder - Delete?

    He can do symbolic link redirection and move the files in it to a different location. *Wink Unable to install Windows due to 2 serperate volumes being marked as C ;)
    Better try it out in a virtual of first. Just a suggestion.

    Like:
    First move everything in c:\windows\installer to d:\installercache
    Then delete c:\windows\installer folder
    Then type this in command mode as admin
    mklink /d c:\windows\installer d:\installercache

    Removing those installer files is a bad idea. it might prevent you from updating or uninstalling apps.
