I also note that (after taking about an hour, to remove the Debian 7.8
installer iso "removable media" disk from the computer, that, like
Ubuntu, the Debian 7.6 LXDE LiveCD does not, using the file manager,
show Properties for partitions, and, in opening a partition, to show
its contents, whows at the top of the tab, as the partition
identifier, a string about 32 characters long, that has no relevance
or application, to the Debian Linux 7.8 installation iso image, rescue
mode, list of partitions, from which to select, to install the root
system.
So, after about an hour and a half, today, I now have to reboot the
system into the PC-BSD -> botched bootup -> GRUB, and use the
vandalised GRUB, to find which partition, is which.
