    I am running Windows 7 on my laptop. I am also trying to extend some unallocated space to my C drive in Disk Management and find the Extend option is unable to work. I don’t know why. Do you know anything about it? Is it still possible for me to extend my C drive successfully? Any solution would be greatly appreciated here!

    Afaik this needs unallocated space next to the partition you're trying to extend. Not sure whether this can be done while system is running. There are loads of bootable partition tools that should do the job.

    Recommend to backup data first, as messing with the partition layout might end fatal :cool2:.

    Laptop with OEM Windows ?
    If So then there might be Reserved Recovery Partition.In this Situation its Risky to change C Drive Disk Size.
    If Not then
    what is the Size that some unallocated space you are trying to Extend.
    Its Better to give Details Of Disk which Shows in Disk Management with Drive Labels(If it Contains Some OEM Recovery Partition )

    This, you can't extend into allocated space. You have to create unallocated space right next to the space you wish to grow. Do this by shrinking the adjoining partition. Then you can extend into that unallocated space.

    Is the unallocated space behind your C drive?

    The “Extend” option in Disk Management often works when your unallocated space is consciously behind your C drive. That’s probably why you cannot extend your C drive there.

    But, don’t worry! There are other solutions for you. You also can take chances with some partition resizing tools like IM-Magic Partition Resizer Free, GParted, EaseUS Partition Master and more.

    Note: If you don’t want to lose your partition data in the process, you’d better back up all partition data on safe places in advance.

    Maybe the poster has found a solution. There was only first post and then nothing else.

    Well , windows built-in tool is not flexible very much. I suggest you goolge and find a third-party partition software. You can also watch how to do from youtube.

    Not very likely it might end fatal, however those third party tools are necessary to achieve this goal. It's a low likelihood bad scenario to happen, thus I do recommend Minitool Partition Wizard, latest version. :rolleyes:

    Yes like other members I also do prefer third party tools for partitioning e.c.t usually show you a sliding scale so you can envisage what is happening and you also have the option of some form of recovery. With windows disk management we still work in MB rather than GB obviously due to it just being a front end for Diskpart.
