How to easily merge two partitions (C and D drive) in Windows Vista

Here are simple steps on how you can easily merge two partitions (C and D drive) in Windows Vista.

Follow the simple steps below:
  • Click on Start in Vista.
  • Go to Control Pannel (Follow steps pre-fixed 'A' for "Control Panel Home view" / 'B' for "Classic View").
  • A: Click "System And Maintenance" (in green).
  • B: Click Administrative Tools (the one with a big gear icon).
  • A: Under Administrative Tools, click "Create and format disk partitions" (If a UAC prompt apears, click continue).
  • B: Click "Computer management" (If a UAC prompt apears, click continue), Next click "Storage", then "Disk Management".
  • On the list provided, right-click the letter drive you want to rid yourself off (say D:) and choose the option "Delete Volume".
  • If you have done it right, a black area should appear within your entire disk space.
  • Finally, right-click your drive you want to add the space to (say C:) and choose "Extend Volume" (by default, the wizard will choose ALL unallocated space to add to your Vista partition, but you can change that if you'd like.)
Hope that helped. Do let me know if you run into any issues with the steps.


  1. This may applicable if the partitions are resided in the master disk.
    Am I correct?
    If I have the partition in slave,will it work?

    Do you mean both the partitions in Slave Venkatesan? Or a partition in master and another partition in slave?

    Well, in first case it will work fine but not in second as both are physically different media.

    Ok I have deleted the D drive. The empty space comes up green and I can't extend the C partition. The option won't highlight. Any ideas.

    Hi, I have Drive C, D and E on same hard disk, I delete D and try to merge it to E, but it didn't work. Do you know why?
    Is there a way to change drive letter E to D?

    Hey guys,
    if your partition has a green bar on it, the partition hasn't been deleted yet. Just right click on that partition and click 'delete partition' again. This time it will become balck and then you can extend the partition that you want to extend succesfully. Hope this helps!

    Hello Jason!

    Several have asked the question, "How do you merge your deleted drive with drive C:, when the Extend Volume option is greyed out, and therefore unselectable"?

    I have deleted my drive E: and it is now black, I want to merge it to my drive C:, but the Extend Volume is not selectable! If I check my drive D:, the Extend Volume option is available! However I do not want to Extend the drive D:!

    Thank you for an answer in advance!

    Right click on your deleted(greyed) drive E and make it Active.

    Once the drive is active you will get the option to "Extend Volume".

    Hope that helps.

    I used EASEUS Partition Master to sort out the issue. It is free for home use.
