My system has three primary partitions: two NTFS (one "system-reserved") for Windows 7 and one ext4 for Linux. How can I shrink the ext4 partition from Windows?

I've tried the built-in Disk Management tool as well as Paragon Partition Manager and MiniTool Partition Wizard, and neither tool seems able to shrink the ext4 partition. What can I do?

  • Why do you have to use Windows? There’s plenty of “live” systems available for both USB drives and CD/DVD.

  • You either need to add the drivers required to do this ( which will not happen through the built-in tool ) or use an OS that does. The driver can be added through third-party tools.

  • Thanks but I was wondering how to do that.

  • I'm trying to do this for a Raspberry Pi drive. Using a boot loader to do it could cause issues because all my USB devices and hubs and my GPU need to be compatible. Or, I could do it in Windows with a known-working system.

I suggest you download Gparted or PartedMagic and create a boot disk; then you can shrink any partition you like.

  • This does not answer the OP's question. The question was how to shrink an ext4 partition from Windows. You have suggested creating a boot disk and rebooting, leaving Windows behind. Jul 28, 2014 at 13:34
  • @ChrisInEdmonton : What's the difference, does the partition need to be shrunk or not? I'm not arguing with you, go on and decrease my credits!

  • Your approach will certainly work, it's just that it doesn't solve the question posed by the original poster. I'm not sure why Morot needs this to happen in Windows. Jul 28, 2014 at 14:36

    That's what I ended up doing.
