I have been trying to dual boot my 2008 Macbook Air with Windows 10 and Ubuntu. The 16.04 live DVD boots but does not offer the option to install alongside Windows 10. When I try Gparted to shrink the Windows partition, it doesn't let me. I even tried shrinking the partition in Windows, this worked but then the Ubuntu installed didn't recognise that the partition had shrunk, nor did GParted. Has anyone got any ideas?
