Failed to start vboxadd.service (on boot)

[Xorcist]

So I recently installed LL4.0 from the ISO onto an Acer Aspire-E500, and the boot takes way longer than it should.

Referencing the boot.log (see attachment) I see ton of:

  A start job is running for vboxadd.service (1min 39s / 5min 2s)

entries followed by:

  Failed to start vboxadd.service.
    See 'systemctl status vboxadd.service' for details.

Any ideas why this is happening (and or how to rectify it)?
