Windows 10: I have two partitions of a drive and when I delete the D: disk, the extend option on the C:...

The far right disk is the one I am trying to merge back into the C: drive.

Deleted Disk Drive D

Hi S -

This is Orlando, an Independent Advisor and an expert with windows 10. I understand you're deleted your D drive to expand your C drive but the option is grayed out.

Is the C partition and D partition are on the same drive or disk?

how are you trying to expand the C drive?

If the drive D is a separate drive then extending the C drive will not be possible as they don't share the same drive volume. You can take back the D drive again by allocating it on your computer. To do that;

1. Open the disk management by pressing the windows key + r and type diskmgmt.msc

2. Once open, you will notice an unallocated space below which is the deleted D drive, you can just right click on it and select New Simple Volume. Follow the instruction next to re-allocate the drive D on your computer.

3. Once drive is created, it will automatically assign a letter on the drive and you can check it on the file explorer.

However if the D drive is on the same drive as your C, you can use the process below to extend the volume of your C drive;

1. Open command prompt with administrator access

2. Type DiskPart and press enter

3. Type List Volume and press enter. It will list all the volume created on your drive including unallocated space

4. Locate what volume number your C drive is allocated.

5. Type Select Volume X >> where X is the number that corresponds with your C drive.

6. Type extend and press enter >> partition C will be extended with the unallocated space on your drive.

Limitations of Diskpart to extend C drive :

* Only when there is adjacent unallocated space on the right side of the to-be-extended partition, extend command is valid.

* Only NTFS partition is supported to extend. Namely, the FAT32 or exFAT partition cannot be enlarged.

* Unallocated space is not displayed in the command window, so you don't know whether there is and where it is.

* Operations cannot be undone, the incorrect operation could cause data loss.

The above method should extend your drive C if it meets all the requirements needed to extend the drive.

Hope this help, have a good day.

Thanks,

Windows 7 Drive C extend partition

Hi,

I have a problem extending my drive c partition, here's the scenario:

Basically, I have 2 partition, the drive C and drive D. Since I am no longer using the drive D i want to delete the partition and add it to drive C.

Heres what I've done,

I navigate to disk partition manager and delete the Drive D partition after that i right click the Drive C partition to extend its storage but the extend button is disabled.

Next, I use my bootable windows 7 installer and choose the advance method installation, there, i was able to extend the partition, but, i want to know if extending the Drive partition will remove my drive c data ? I dont want that to happen. . I want just
to extend its storage thats it. So that i can be only using Drive C.

Thanks. .

 

how to merge c drive and d drive

It depends on a couple things.

If you have two separate physical C and D drives, you can't merge them.

If the D drive is a partition (not a drive) and its to the right of C:\ in Disk Management, you can right click C:\ then click Extend.

Press Windows key + X

Click Disk Management

Take a screenshot then post in a reply here.

If the layout is similar to how I described it, try the following. Make sure important data is backed up if there is any.

Select the D:\ partition

Right click the ‘D:\’ in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

The Volume you deleted will now appear as ‘Free space’, you will also notice that the disk icon no longer appears in the list of volumes.

Right click the Free space partition, and click Delete, click Yes on the Disk Management warning that appears.

The volume will now appear as Unallocated. Our next step is to merge back that unallocated free space with the system partition (C:\). Right click the System volume and click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.

A wizard will now begin that will guide through the steps to merge back the unallocated space with your system partition.

The wizard provides a simple procedure to merge back the unallocated space with the system drive. Once you have selected the space, click Next, at the end of the wizard, you will see the amount allocated.
