    mount: /: /dev/sda2 already mounted on /.

I would like to delay it until after my computer has booted up to speed up my boot time.

    I understand that it is output of systemd-analyze blame, but could you please include this information in question. Also please include output of mount command. dev-sda2.device may correspond to root partition or home partition, they need time to be mounted and checked for errors with fsck (like CHKDSK in windows). And why you opened new question, based on previous one?

    @NObert My question is not based on a previous one. It's a totally different issue.

    See askubuntu.com/questions/948748/… as to what dev-sda2.device is.

You can't delay this until after booting.

sda2 is your Root Partition ("/") so that means this device is the Root of your Entire OS.

The Task that takes so long is mounting this Partition so it can be used.

But it seems that this takes too long, it could be a Driver/Partition Failure (errors shown with fsck ( @N0rbert ) ), slow HDD, something else. We don't have enough information to help for that.
