    Help uninstalling first OS in SSD with win8.1 & 10 dualboot


    Hello is it possible to uninstall the first installed OS (Windows 8.1) in the SSD that has also win 10 installed into the second partition without losing data in win 10? If not from windows tools maybe using some software? Currently this is how my SSD is:

    Disk0: [System Reserved:350Mt][D:233Gt][C:231Gt][Recovery:450Mt] D being windows 8.1

    yes..

    from run type> msconfig
    go to boot tab and delete the entry for windows 8.1
    and then format the D (win8.1) partition

    or use MiniTool Partition Wizard free to delete the Windows 8.1 partition and expand the Windows 10 partition into the free space, if you want to add the space to Windows 10.

    In any case, the system reserved 350mb partition should contain the boot files so you should be safe in deleting or formatting the Windows 8.1 partition.

    Oh, is that not possible (expanding the free space to win10 afterwards) if i do it the way Kyhi said? I guess i should have included that in my message since i want that aswell.

    If you do it Kyhi's way you will end up with an empty D: drive. If you want to add the space to C: drive (Windows 10) you will have to use MiniTool Partition Wizard Free (or some other partitioning program) to delete the Windows 8.1 partition and expand the Windows 10 partition.

    Formating D will leave it as a partition (Data)
    You can also delete the partition - which cause it to be freespace
    and then expand C

    I would choose to leave D as a DATA partition
