Windows 10: Why can't I shrink my C drive with all of the space free?

I wanted to create a Dual boot for windows 10 and ubuntu but when I tried to shrink my partition to create some space to install ubuntu. I couldn't shrink the partition even though I have a lot of storage available. Any ways to solve this? Os: windows 10.

Shrinking of C Drive is Not possible

windows 8.1

i have total space of around 220 Gb in C drive which i would like to reduce and transfer the space to other drive. when i tried the 'Shrink' option, it showed available shrink of around 5Gb which reduced the C drive to 215 Gb.

How to further REDUCE the volume in C drive and Transfer the space to Other Drives?

Help me out.

 

Unable to shrink C: drive less that 480GB in Disk management on Windows 10.

Hello Lex,



Thank you for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.



Before assisting further, I would like to ask you few questions:

a. What happens when you try shrinking
C: drive below 500 GB, do you get any error message/error code?



To create a partition or volume (the two terms are often used interchangeably) on a hard disk, you must be logged in as an administrator, and there must be either unallocated disk space or free space within an extended partition on the hard disk.

The disk space of minimum 4GB and maximum of 8GB should be dedicated to Windows 10 installation files & folders on the drive in which the operating system is installed.



I suggest you to check the possibility of shrinking the drive by 420GB in the Disk management by following the steps below:

• Press Windows logo + X keys on the keyboard and select
  Disk management from the context menu.
• Right click on the C: drive from the window and select
  Shrink Volume from the context menu.
• Enter 504000 in the Enter the amount of space to shrink in MB box and click on
  Shrink.
• Right click on the Unallocated drive which was recently created and select
  New simple volume.
• Follow the on-screen instructions and assign the drive letter from the window.
• After the drive letter is assigned and the procedure is complete, right click on the newly created drive and select
  Open from the context menu.
• Check if the partition is displayed in the File Explorer.

not able to shrink C: even though there is plenty of space free

Some of windows system files got corrupted so i did recover it through recovery drive. Everything was fine until i knew that Windows C: is taking up 500GB of my disk space. I tried shrinking it but it's showing " available space on drive for shrinking
: 0mb "..... Total space : 500gb. Used space : 40gb. Free space : 460gb. Why can't i shrink C: and make use of the free space ?. Is there anything wrong with recovery i've done ? Is there any SAFE WAY to
shrink it ? Please give some solutions.

P.s. : Earlier (before recovery) , C: was allocated around 200gb and was working fine.
