System Partition Full. how to clear the space when it looks empty

The System Partition likely contains your Boot Database Files. I wouldn’t consider deleting it unless you know what you are doing. You would have to move the boot files to another drive and point the OS to where the files are located.

 

The concern of this article is to just clear up the space on the 100 Meg System Partition. There are third party tool that can do most things, but if you just want to get rid of the error then you just do the following. This assumes a EFI installation:

 

A. Getting into Recovery mode Command prompt

  1. Boot to Windows DVD
  2.  Repair My Computer
  3. Choose Troubleshoot
  4. Choose Advanced Options
  5. Choose command prompt

B. Unhide the disk and assign a drive letter

Commands you may run to identify the EFI parition include Bcdedit enter or bcdedit /store C:\Boot\BCD /enum

  1. Diskpart
  2. List disk
  3. Select disk 0
  4. List Partition
  5. Select partition x (where X came from the bcdedit  above or what you saw in list parition)
  6. Detail Partition
  7. Take note of the partition type value– you will need to have it – to hide the drive again – see here
  8. set id = 07 override
  9. assign letter =x
  10. Exit

C: Clear the space 

the command is fsutil usn deletejournal /N /D X: where X is the drive letter from one you just assigned

 

D. Hide the disk and remove the drive letter 

  1. Diskpart
  2. List disk
  3. Select disk 0
  4. List Partition
  5. Select partition x (Which is the drive letter you should be familiar with by now)
  6. Detail Partition
  7. get the original value for type and be ready to use it in the command below – see here
  8. set id = 17 override – it was likely 17 – hidden as i have listed it in case you forgot. 🙂
  9. remove letter =x 
  10. Exit

Your System partition should now not be full we hope!

 

I ran into this a while back and dont want to forget how to go about it. I hope this helps someone.

 

Thank you,
