How did you "download" Ubuntu 16.10?

For diagnostic purposes please provide also the output of the following commands (to be executed in a terminal window):

uname -a
lsb_release -crid
sudo fdisk -l

"... have lost half of my hard drive ..." In what sense?

Your hard disk currently is partitioned into a 248GB FAT32 partition, a 208GB Linux partition, and a 5.9GB swap partition for Linux (the latter two inside an extended partition)

Do you know what the partition layout was before the upgrade from 16.04 to 16.10?

I do not see any indication that there was a resizing action done recently.

Hi Manfred,

Sorry about the delay, but it now takes me longer to get things together than it used to since I turned 70, and I always like to mull over any problems.

to be honest it is really of no consequence that the HDD has appeared with a new division. That's a minor problem once I have a fully functioning OS. The 16.10 that I downloaded from the 'upgrade' internal system from the 16.04 is not functioning as it ought. There are several key activities that do not function, and the most important of these are the non usable CD/DVD reader ( I can find no way of opening it ) and the fact that the keyboard has taken on characteristics that i cannot change ( the setting is now basically US, and the left hand shift, and caps lock are now redundant ). This makes it very difficult for me to write in english.

Once i can get it to function, I intend to replace the present OS with another, possibly 16.04, else Red Hat, or one of the newer European OS's.

PS I'm not afraid of computers, I started messing around with them at Cambridge back in 1967 on the old Atlas, using pure machine code.

Just to make sure that I correctly understand the situation:

"download 16.10": how did you initiate the upgrade from 16.04 to 16.10? did you press a button that offered an upgrade (which then started a download and an upgrade process), or did you browse the web and download something?

"CD/DVD": did it work on 16.04?
"I can find no way of opening it": Doesn't it have some kind of button for opening its tray? What kind of hardware is it?
What happens if you try the command "eject /dev/cdrom"

What is the output of the commands
ls -l /dev/cd*
ls -l /dev/sr0
groups

If you open the system settings - keyboard and then click on "text entry" in the bottom left corner, you get a window where you can add another keyboard layout. If you have more that one keyboard installed, you will see a language indicator on the info area in the top right corner of the screen. Clicking it should allow selecting the correct keyboard layout.

Hi Manfred,

These are the results of the terminal questions that you asked for:

rk@rk-SATELLITE-PRO-L830:~$ eject /dev/cdrom
rk@rk-SATELLITE-PRO-L830:~$ ls -l /dev/cd*
lrwxrwxrwx 1 root root 3 Mar 30 09:54 /dev/cdrom -> sr0
lrwxrwxrwx 1 root root 3 Mar 30 09:54 /dev/cdrw -> sr0
rk@rk-SATELLITE-PRO-L830:~$ ls -l /dev/sr0
brw-rw----+ 1 root cdrom 11, 0 Mar 30 09:54 /dev/sr0
rk@rk-SATELLITE-PRO-L830:~$ groups
rk adm cdrom sudo dip plugdev lpadmin sambashare
rk@rk-SATELLITE-PRO-L830:~$

Using the system settings produced no result, however using the info area at the top it has reverted to UK Eng, but still has the caps lock and left hand shift blocked out.

The "CD/DVD" worked well on 16.04, and I download 16.10 from the 16.04, using the upgrade button.

I have found an old (2011) Samsung DVD writer model SE - 208 which seems to work with my Toshiba SATELLITE-PRO-L830, the laptop in question. using 16.10 It appears as Audio Disc and runs under cdda ://sr1/

Hope this info is useful.

Does one of the CD/DVD drives have a button that you have to press for opening the tray?

Have you tried other keyboard layouts? Are you sure that the shift and caps lock keys aren't defective?

Hi Manfred,

I got the cd/dvd open using the eject /dev/cdrom command. ( the gate only opened a fraction, and the rest of the travel was very stiff. WD-40 worked wonders. I think your suggestion of a default, may really be a spillage onto that part of the keyboard, so am off to buy a switch cleaner for the the keyboard.

Thank you again I think you have solved my problem
