    Windows 10 upgrade deleted partition


    Hi

    I have just update my pc from Win7 to Win10 and before upgrading i had 2 discs showing, C & D.

    There was instruction that i had to delete partitions before upgrade.

    After upgrading I checked My Computer and only disc C is listed.


    I obviously accidentally deleted partition for D drive.

    Is it possible to restore what has been deleted without having to purchase any programe to do this


    Thanks


    Tony

    :)

    Delete my W10 Partition

    Do you want to safely delete your Windows 10 partition and use only Windows 7?

    If Yes, then boot to your Windows 7, run msconfig, go to "Boot" tab, you will see something like this :

    Choose "Windows 7" and click "Set as default", then choose "Windows 10" and click "Delete", restart if asked or necessary.
    Now the boot information for Windows 10 has been deleted and you can safely delete your Windows 10 partition (make sure no important files are on the Win10 partition). To delete and extend your partition you can use many partition manager tools.

    W7 Hard drive partition issue

    to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

    - press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
    - diskpart <-- start the windows command line partition management tool
    - list disk <--- list the installed hdds in this computer for the next step
    - select disk 0 <- might have to replace 0 with the number of the correct disk
    - clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
    - create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
    - exit, exit to exit diskpart and the command prompt
    - click refresh in partition manager and select your newly created partition and install to that
