I wish to install Linux Mint Debian 2 alongside Linux Mint 17.3. When I get to the partition screen, do I put the mount point on sda1 where Linux Mint 17.3 is or on the partition I created for Linux Mint Debian 2, which is sda3? I want each edition on its own partition, each with separate /home and able to choose which edition to boot from on the boot up GRUB screen. Thanks.

If you have Mint on sda1 and are installing Mint Debian, you need to put Mint Debian on a different partition such as sda3. If you select sda1, you will overwrite your other Mint install. In the main window, click on sda3 to highlight it then click the Change tab below for the edit window and select / from the Mount point menu. If you want to use Grub from Mint Debian to boot both systems, select to install Grub to /dev/sda under the device for bootloader installation. If you want the original Mint to boot both, select to install Grub to sda3 where you are installing Mint Debian.

The above only applies to MBR installs. If you are using UEFI, ignore the bootloader section above.

Hi.You should have 4 partitions then (and maybe a swap) unless you mean to do the basic setup all files in one partition? In witch case Yancek...

Installing the second operating system I normally just skip install GRUB, then boot into the first and runnext reboot should have them both.
