:)

 

Need to delete an old healthy Recovery partition.

Press Windows key + X

Click Disk Management

Select the Recovery Partition

Right click it, click 'Format'

You will receive a Warning dialog, click OK to continue.

The next step is to select your file system option, in this case, go with the default which is NTFS.

The formatting process will now begin.

Once complete, the drive will be displayed as a ‘Logical Drive’ in Disk Management.

Right click the ‘Logical Drive’ 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. Right click the System volume (usually the C:\ drive where Windows is installed) then 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.

 

Resize partition C

In order to extend C and recover space from D, you will need to delete the 866 MB Healthy Recovery Partition and the Storage D:\ partitions.

There appears to be data on the D:\ partition.

I recommend you backup any important data on that partition before deleting it. After deleting the partitions, you will be able to extend C:\

Storage (D’ partitions in Disk Management, on the contextual menu, click the ‘Delete Volume’ option. Click ‘Yes’ when the warning dialog appears.

(C. Right click the System volume then click the ‘Extend Volume’ option on the contextual menu, click ‘Yes’ when the warning appears.
