Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

OK, I am new to Linux & took a bit of a punt on choosing to install Zorin as opposed to other Linux OS like Mint Mate etc.
I was really pleased for the first couple of days - great GUI, fast & responsive (I only have a celeron). But this morning the computer (Zorin 8) wouldn't boot- it gives this message almost immediately after turning on the computer-
error:failure reading sector 0 x 8 a 8 from 'hd 0'. Entering rescue mode. grub rescue>
The night before I created & saved a couple of Libre Word Processor documents & saved them to the internal hard drive- I obviously now can't access them - which is incredibly annoying.
What does this error mean?- does it suggest there is a problem with the Internal Hard Drive? (I do suspect there is a problem with the HD) And how do I go about at least recovering those 2 Libre documents &/or getting the computer back working?
If you still have the Live CD (or other medium) you used to install Zorin, you can boot it up, mount the partition on which you had Zorin to access the files you are looking for and then copy them to some other medium like a flash drive. If you are unfamiliar with these terms, I would suggest that you boot the Mint medium and open a terminal, then run this command: sudo fdisk -l(Lower Case Letter L in the command) and post the output here. Someone should then be able to give more specific instructions. You might find something sooner by doing an online search.
root@sysresccd /root % sudo fdisk -l
zsh: correct 'sudo' to '_sudo' [nyae]? y
_arguments:comparguments:312: can only be called from completion function
root@sysresccd /root %
so I them tried fsarchiver (see below) - me trying to interpret it below - shows sda which is an external Seagate 1tb HD, the sr0 is the SystemRescueCD - so in both of these commands, (as far as I can interpret - the Internal Hard Drive (where teh Zorin OS is installed & the Libre documents I saved- isn't recognised. I also tried gparted - but once again it gives a 'no partition' status
It's asking me to find the menu.lst file which should be in /boot, but is not
Might be. The command I suggested would have worked using Zorin or Mint CDs as they use sudo and I don't believe SystemRescueCD does. Instead, using the SystemRescueCD, you could try in the terminal typing: su -, then hit the Enter key and type: fdisk -l, hit Enter and see if you get output on your drive. The link below explains how you could run a filesystem check which may help.
given that it now appears to recognise the internal 500gb hard drive (beats me why now) so I went to the HD through the 'Computer' folder - when I double clicked on the HD's icon - I this pop-up error message
Unable to mount drive-Error mounting /dev/sda1 at /media/mint/bcf2eaf3-bc30-4b56-8600-ca68c77b15af: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sda1" "/media/mint/bcf2eaf3-bc30-4b56-8600-ca68c77b15af"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sda1,

In some cases useful info is found in syslog - try
dmesg | tail or so
