I am trying to install my first `Linux` system and I am stuck setting up the hard drives. Given my lack of experience I decided to use the guided setup from the hard drive setup screen figuring I would go back after the completed Debian installation and simply resize my drives as needed.

However when trying to run 
```
sudo service lvm2 start
```
 I get a message "unit lvm2.service is masked".

Any ideas as to why this is happening? all I could find was a note that LVM as not compatible with grub `/boot` and should be outside the storage disk managed by LVM.

If so is it truly referring to the entire disk on which `/boot` is loaded or can it be simply a separate logical partition on that disk?
