Can't shrink Windows partition?

Fragesteller729ByFragesteller729

Hello! Today I wanted to create a new partition for dual-booting on my Windows 11 laptop and thus shrink the other one. However, when I did the shrinking, the maximum size in MB was 1900, even though I still have 80GB free on the SSD.

You can see what is in the event log in the picture.

PC goes into sleep mode even though it was actually deactivated?

BySpeedEnforcer

Good morning I've noticed that recently the sleep mode settings on several devices seem to be ignored – this affects Windows 10 and Windows 11 in various editions (including LTSC and LTSB). I have to say that I'm actually very well-versed in Windows and definitely not a beginner, DAU or anything like that, and I…

Windoof is waiting for you from less obvious stupidities :P.

More precisely, you tried to saw around the branch you sit on.

Solution: You have to put yourself on another branch.

You can (and should) never change the system partition of the operating system that is currently running.

You have the following options – depending on the planned distribution on the Linux page:

  • You reduce Windows partition during Linux installation
  • Your installation stick is a live bootstick at the same time, so you can use (g)parted
  • You’re making a Ubuntu installation stick. It’s also a boat stick

How I would proceed (and possibly have no idea of Linux :D):

  1. Make Ubuntu installation stick (if the desired distri also has a live installation stick, it’s likely to be)
  2. If you don’t have: create Windows installation disk (if anything goes wrong)
  3. Secure all important data carriers (full backup)
  4. Remove all external data carriers in advance (better: for the entire installation process until both operating systems run completely)
  5. Boot via Ubuntu stick and call gparted -> Open terminal window and: “sudo gparted”. If gparted is not installed: “sudo apt-get install gparted”
  6. It opens
  7. You select the hard drive where your Windows is on it.
  8. Really chosen the right plate?
  9. Really backup made?
  10. Enough time?
  11. If it is a laptop:
  12. You select the large Windows partition right and reduce it so that the second operating system has enough space
  13. This process can take a long time and even if the process seems to be stuck: if you break it off, it was with the Windows partition. So wait!
  14. You create a partition with the file system “swap” at the end of the free area, which is twice as large as the size of your RAM.
  15. You create an ext4 partition from the remaining free area

Ready. PC reboot that you’re back in Windows. See if the Windows is still running error-free.

Now you have created the optimal conditions on the hard drive to install the desired Linux.

Now use and play the installation stick of your district. The prepared ext4 partition during installation as root partition “/”.

The Swappartition has two important tasks:

  1. You can put your computer in low sleep mode (where it really goes out), where the RAM is written into this partition
  2. The partition serves as a “extension” of the RAM if it is not enough (as it does the outsourcing file under Windows)

Windows cannot move system files within the partition, i.e. if there is a system file at the end (as here the bitmap of the occupied blocks), it is with reducing vinegar.

Build a USB stick Gparted (and secure before doing so important data on another disk / USB etc.).

With me it has helped if you right click on the drive do dund at “properties” > “Tool” under optimize, defragmentirest. Can also help with a ssd.
if it doesn’t work, we’ll see on.

isn’t that harmful to an SSD?

So just get some more write cycles. But actually not. If this is very old, then I wouldn’t do it, but in your case I think it’s not a problem.

edit: there’s a comment on your error message where you can run a command in an admin terminal. You can find more about the file that prevents it.

I’ll try https://www.minitool.com/partition-manager/partition-wizard-home.html

Isn’t open source, but freeware, and since I don’t know how good you can use command applications, like gparted, this is my recommendation

For times off (if drive/volume is not C, change C on the corresponding letter)

chkdsk C: /F /R

that checks the volume after error, you are prompted to restart.
Then try to restart at least 2 times. This is such a sometimes working trick.
does not work the Dan, we may need to use 3.

So the optimization has not helped and the command just came that it is used by Bitmap

Here again the result: C:\Windows\System32>fsutil volume querycluster\?\Volume{7ad09fde-47c3-4c61-ba8e-0bdf600fb4ac} 0x3ae6f49

Cluster 0x0000000003ae6f49, used by -S–S \$Mft:$BITMAP

Or does it help restart the PC?

If it’s in the message, there’s a system file that can’t be moved and that’s why only the space can be released after that.

Both the operating system and some programs use this function to check / secure the legality of an installation

Yes I know but there is some way to fix this because defragmentation is not going on an SSD
