Remember that /tmp does not use disk space. It's a RAM filesystem.

If you modified the fstab, you could have just changed the current /home line to point to the new partition instead.

During the installation /home is now on the SSD. Can I make a symlink to an new /home at the HDD-drive?
As I mentioned before, the easiest way would be to do a reinstall. Since the /home partition is on the SSD right now, if you put /home somewhere else, that space will be lost. You most likely would want that space in your root partition instead.
So I did a reinstall (i.e. several reinstalls). Fast boot is disabled.  I chose custom partitioning.

I can put /home on the HDD all right. But now I can't mount the Windows /boot/efi partition. I have read that when you install fedora alongside Windows you must not have two /boot/efi partitions, because Windows can't handle that and won't boot.

I select the (Windows) /boot/efi partition in Anaconda installation screen and fill in "/boot/efi" in de mount-point window in the right side of the screen. At first this seems to work, because this appears under "New Fedora 28 installation" (left side). But when I have finished assigning mount-points and hit the "done" button, a error message pops up.

"No valid boot loader target device found. See below for details.

For a UEFI installation, you must include an EFI System Partition on a GPT-formatted disk, mounted at /boot/efi."


I googled and found out that my problem is not unique, though I did not find a solution that worked for me.
