I have a dual-boot laptop with both Windows 10 and Ubuntu 16.04.
Currently, the Windows side has too much disk space, and I want to resize things so that the Ubuntu side has more.
Firstly, I went into the Windows disk management and shrunk the Windows partition by 20GB. I then wanted to expand the Ubuntu partition, but it seemed like this option was greyed out.
Can I expand the Linux partition from Windows or do I need to be in Ubuntu or do I need to create a boot disk and do it that way?
Or do I need third party software?
Any help gratefully received.
