How to shrink one volume to extend another?

Hello Experts,

I would like to shrink my main primary boot partition containing Win 8.1 (C:), so I can extend my Win 10 preview partition (E:) which is adjacent and to the right of C: (Please see attached screen capture of my disc configuration). I need to do this because I failed to create enough space for the Win 10 installation and I'm running low on usable disk space.

Is this doable using the Win disk manager or do I need a 3rd party tool?

Thanks!

You can easily shrink C: with the built-in Windows boot manager; but you can't "slide" the E: partition to the left so it can be extended without using a 3rd party tool.

I'm also a bit fan of Boot-It BM, but it will NOT work for this without a bit of change to the system, as it can't boot on a UEFI system. If you disable Secure Boot and boot in legacy mode it will work ... and I suspect the same thing is needed to use GParted (which is clearly what andreas meant to suggest).

Note also that the process nobus suggested will NOT work => after you've resized C: you will have to SLIDE the E: partition before you can extend it.

Don't bother using 3rd parties. Make an image backup of e:, shrink c:, replay e: - done.

Thanks for the 3rd party tool suggestions. I ended going with the free version of Paragon v 15 and it worked perfectly.
