So I have a dual boot setup using Windows 10 and Linux Mint 17.2 but I can't boot into Mint normally because my laptop always boots into windows without showing grub.
In order to boot into Mint I have to hold F12 while booting, select my HDD and then select 'ubuntu' or 'Ubuntu' from a list of items, which brings me to grub. From there I can boot into windows and mint.
How do I fix this? Using boot-repair didn't work and neither did reinstalling Windows or Linux.
