Hello guys! When i got my pc, i installed Windows 7 on it and after a while i switched to Windows 8 but still had W7 on dual-boot. A while later, i got Ubuntu too and now have 3 OS's. My question: How can i delete the partition W7 is installed on (for adding the space to another partition)? I found something online about moving the bootmgr to the other partition.. or duplicating it. Any help will be appreciated! Thank you in advance.
