What to do if your laptop hard disk fails to partition
First of all we need an auxiliary software, section assistant, everyone download themselves. Then install.
Open the Section Assistant. We can see some basic information about our current hard drive.
Let's take a look at this part of the red box in the picture below. We are unable to operate, and other disks can be repartition according to our own needs. Here I will tell my own C-disk expansion, to do a demonstration.
First, we choose to separate out the extra space in our other disks. Here I choose my own e-disk. First select your own e-disk, in the Select Adjust/move section.
The following dialog box appears and we drag the icon in the red arrow to change the size of the current disk to separate out the extra parts.
Then click OK and we will find an unallocated space next to E disk, then click on the Space and right-click to select Merge partition. Select the hard drive you need to enlarge and click OK.
We have found that we have allocated the space of e disk to the C-disk.
Finally click Submit, the computer automatically restart after the completion of the OK!!!
