Partitioning disk space to install Ubuntu

Hello,

I am trying to partition disk space to install Ubuntu and I tried to use the disk management tool. However, it gives me the error message:

"You cannot shrink a volume beyond the point where any unmovable files are located. See the “defrag” event in the Application log for detailed information about the operation when it has completed."

Trying the advice on this website:

https://www.winhelponline.com/blog/you-cannot-shrink-volume-beyond-point-disk-mgmt/

does not help.

Going to the Application log shows me that there is a problem with a C++ Redistibutable.

- The last unmovable file appears to be: \Users\...\AppData\Local\Temp\postgresql_installer_02a15c3dd9\vcredist_x64.exe::$DATA

- The last cluster of the file is: 0x39f38a5

- Shrink potential target (LCN address): 0x2922823

- The NTFS file flags are: ----D

- Shrink phase: <analysis>

How can I partition my disk space to install ubuntu with this problem?

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.
