Hi Aere,

The OBI does not clone, it makes tarballs, which is an advantage,
because it does not need a drive or partition of the same size or larger.

Making a tarball works if your whole system is in the root partition (it
does not manage a separate home partition). You should use the same tool
(also same version) to make the tarball and to use the tarball.

For example, the standard OBI is built into Lubuntu Trusty. Israel is
creating ToriOS, which is built from Ubuntu mini Precise. If you use
Israel's ppa, keep track of the version of the host system (where you
install it, and use the same Ubuntu version for both making and using
tarballs, otherwise the installation will fail, I think because of
differences in grub between Ubuntu versions).

-o-

*At the basic OBI level*, you select drive and the installer uses the
whole drive, makes one root partition and one swap partition. This
corresponds to the basic mode in the Ubuntu standard installers - 'use
the whole disk'.

*At the advanced OBI level*, you are expected to re-use existing
partitions or create/edit partitions with *gparted* before starting the
OBI. You select the root partition and the swap partition from menus.
This corresponds to 'Something else' in the Ubuntu standard installers.
It is easier to use, but does not have all the bells and whistles. If
you add the following labels to the created partitions in gparted:

obi-root
obi-swap

the installer at the advanced level will find and select them
automatically. It helps but is not necessary.

-o-

In both cases, if there are other operating systems that you want to
dual boot, boot into the now installed ToriOS and run

sudo update-grub

which will make a new grub menu with all recognized operating systems.

Best regards
