Delete partition with old Windows Install

[Bloody Spy]

So i just installed Windows 8.1 on my ScrapMachine.

The 8.1 install is on one partition the older one is in another partition.

I want to delete the old windows partition and unify the unnalocated space to the new one.

Windows won't let me.

It keeps saying i can't clean or delete it because either it is a  boot memory leak or other thing. Even when i tell OVERRIDE.

Halp ;-;

method that will work 100% is boot Linux from usb and remove it while in live mode. Just don't remove your current partition
