Windows 10: How to extend the size of existing partition in Windows 10?

Hello, I'm running a dual boot on my computer, but the other OS is running out of space. I want to extend the size of it on diskmngt but it is greyed out. Already tried the following that I did to shrink a volume but nothing works.- Disable System Restore- Disable HibernateIt is currently 50GB under a healthy partition, I want to make it 100GB, as I still have huge free space on my main drive. How can I do it? Thanks!

Extend C drive Size

Your Image does not show a D partition. It does show an F partition which if reduced in size would enable you to increase the size of the C partition.



These are the steps needed to enable you to increase the size of your C partition:

• 
  Reduce F by 20 gb placing the unallocated space before F.
  
• 
  Increase the Recovery partition by 20 gb taking up unallocated space created by Step 1.
  
• 
  Reduce the Recovery partition by 20 gb placing the unallocated space before the Recovery partition.
  
• 
  Increase the C partition by 20 gb to take in the unallocated space before the Recovery partition.
  

You can use Easeus Partition Manager (freeware) to carry out these tasks. The files in each partition are automatically moved when you carry out each step detailed above.

How to extend C partition

Hi Kevin,

Thank you for the information provided.

Please to inform you that you need to have an “unallocated disk space” to the right of the Partition\Volume you wish to extend on the same drive. Only when “unallocated disk space” is available “extend” option is highlighted.

I suggest you to try these steps and check if they helps.

Step1: Press Windows + R and Diskmgmt.msc and try the following

a. Right click the basic volume want to extend.

b. Click extend volume.

c. Follow the instruction on the screen.

Step2: Open a command prompt and type diskpart.

At the DISKPART prompt, type list volume. Make note of the basic volume you want to extend.

At the DISKPART prompt, type select volume <volumenumber>. This selects the basic volume volumenumber that you want to extend into contiguous, empty space on the same disk.

At the DISKPART prompt, type extend [size=<size>]. This extends the selected volume by size megabytes (MB).

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.
