    Unable to extend volume


    Hi, I upgraded the internal SSD drive to 1tb and successfully restored my original OS, however there is a 454.57gb unallocated space as seen below:

    When I try to extend the volume, the unallocated space does not show up, as seen below:

    Any fix? Thanks

    The easiest way to do that is to get Minitool Partition Wizard (free)
    Best Free Partition Manager for Windows | MiniTool Partition Wizard Free


    Install the program then do this...

    1. "Move" all the little partitions (to the right of the C:\ drive), all the way to the left (one at a time).
    2. Then the 454GB unallocated will be right beside the C:\ drive.
    3. Then, just right click the C:\ drive and choose: Resize, and thereby add all that unallocated space to the C:\ drive.



    Another option....

    Just right click the unallocated space and make it a new partition, like D:\

    There are many partitions after the C: partitions, most of them are useless.
    As you still has the original drive as a backup, this is what you can do:
    - Disable Recovery
    Open a CMD window as administrator and type:
    reagentc /disable
    - Delete all partitions to the right of C:
    The 990M is probably Recover partition
    The 10G is probably the Factory recover. Useless as Win 10 has been updated many times
    The 1G is probably tools to do the Factory recovery, also useless.

    Use Minitool to delete the partitions. Once you have one and only one unallocated space to the right of C:, expand C: to the end and hit apply.
    Now you should only have:
    - EFI - 100M - Fat32
    - Reserved - 16M - RAW
    - Big C: NTFS

    Recreate a new Recovery partition
    Open a CMD window as administrator and type:
    reagentc /enable

    Now you should only have:
    - EFI - 100M - Fat32
    - Reserved - 16M - RAW
    - Big C: NTFS
    - Recovery - ~800M - NTFS


    Another option is to clone again the original drive, resizing the C: partition before it starts.

    Another option in my 'toolkit' is the GPARTED LiveCD, boots outside of Windows to manipulate partitions when Windows won't allow it.

    Yes, I did that from a WinPE environment, I deleted all partitions to the right and then merged the main OS partition with the 454.57gb partition and the system boots fine.The C drive now looks as seen below. What about the 500MB partition to the left of C, is it safe deleting that one too and then merging it, or is that partition necessary for booting? Thanks everyone for their replies

    Can't see the recovery partition.
    Did you disable with reagentc /disable?
    Try to enable with reagentc /enable

    It will when you need to enter the Recovery environment to fix things.
    You should had disable it before deleting the partitions.
    Try now
    Open a CMD window as administrator and type:
    reagentc /disable
    reagentc /enable

    All of the functions of the Windows Recovery Environment are available when you boot from a Windows 10 installation USB flash drive (or DVD). So the lack of being able to enable the recovery environment with reagentc /enable is no big deal.

    And yes, there is a very good possibility that you need the 500 MB EFI System Partition. The UEFI specification requires that all UEFI systems must be able to boot from a FAT partition (usually FAT32). Since the C: drive partition is NTFS, the EFI system partition (FAT32) is there to maintain compatibility with all UEFI systems.

    Some motherboard manufacturers have included the ability to boot from NTFS partitions in their firmware. If you have such a motherboard, then you could transfer the boot files from the EFI System Partition to the C: drive partition, delete the EFI System Partition and boot the computer from the C: drive partition. So, the question is, does your motherboard have that capability?

    And if you are going to ask, how would I know? Well, you would transfer the boot files from the EFI system partition to the C: drive partition and delete the EFI System partition. Can you get the computer to boot? If not, then your motherboard needs a FAT partition to boot from.
