Q:

How to hide filesystems from the launcher in unity

Sorry if this is a silly question - I'm not really experienced in Ubuntu.
I have recently enabled my Chromebook to dual-boot with Ubuntu using crouton. In the launcher, I can see some applications, but also 3 file systems. I think that they're partitions of the solid state storage on my laptop - they won't open and it gives me an error, which is fine because I don't need to use them from Ubuntu, but is there an easy way to hide them from view? I don't want to unmount them in case it mucks things up.
Thanks,
Archie

A:

Open up disk utility by pressing pressing Ctrl+Alt +T and type in
gnome-disks

Click on the gear icon then click on Edit Mount Options.

Set Automatic Mount Options to Off by clicking it.
untick "Show in user interface" just like in the screen shot. then click OK.

after this step you will need to remount the drive if the drive is not mounted. then you don't need to do any thing.
and now it should be gone from the user interface.
