Installing Ubuntu OS on SSD and install HOME on other HDD [duplicate]

Choose "something else" when Ubuntu asks, during installation, about the installation target.

You will be able to choose directly to install Ubuntu system root partition (/ mountpoint) to a partition on the SSD, and choose to install /home on the regular HDD partition. You will be able to create, modify and format the partition in that part of the installation.

• Choose free space for the root partition on any drive (here /sda), and press "Add..." to choose size and mountpoint:

• Do the same for your HOME partition on your harddrive. Choose montpoint /home:

Check that everything is alright (e.g. make sure the "format" option is unticked for your Windows partitions) and proceed with partitioning and installation of Ubuntu:

To have /home in a different partition from /, you'll need to do this:

1. Make home the top-level directory on the partition you want to contain it.(on the Hard Disk)

2. Give the partition that contains home its own mount point. A reasonable name for this is home (unless you plan to use that partition for other stuff too)

3. Give /home its own entry in /etc/fstab.

4. Make /home symbolic links to /home/home.

Another approach is to install ubuntu normally in the SSD then move home folder to HDD following this official article from ubuntu
