I've tried to install several times so far Linux Mint 19 alongside Windows 10. Windows 10 is the primary OS.
I installed Linux on
/dev/sda making manually a swap area, root and home partitions and when the installation is finished and I restart and the system boots automatically in Windows like there was a single OS installed.
What I'm doing wrong and how to fix this issue?
Before I couldn't access to Windows nor Linux, so I was able to fix the Windows boot following this steps, then the Windows boot partition now is FAT32 EFI.
Run command prompt from Windows installation DVD diskpart sel dis 0 sel par 1 del par override cre par EFI for fs=FAT32 quick assign letter=T exit bcdboot C:\Windows /s T: /f ALL exit Then reboot the computer
