When did you system crash? On startup, on restart, on hibernation, while 
running, which desktop?
Other times: system crashed more often when viewing video material.
This time: during the "installing" portion of the upgrade from zypper dup.
Using ext4. When I installed system (last summer) made a /root and a /home partition
but everything wound up on the /home, nothing on /boot. Obviously I did
something wrong, but I don't know what. If there is specific provision in
the install routine for separating /boot and /home I didn't see it, but would
very much like to when I reinstall.
Desktop is KDE 5. 
updating would correct this, I ran zypper dup. and it crashed while 
installing

This is always a bad idea when you have a problem like that. What file system 
you use. If you use BTRFS the only advantage of it is, that you can rollback. 
Do you use BTRFS? Do you  know how to rollback?
I don't use BTRFS and hope not to, as it is more-or-less non-standard,
and GParted knows nothing of it.everything.

It is now not possible to boot the system, either on the main
versions or the recovery versions. I can only get as far as the light-bulb.

      

      
Chances are good you did interrupt the install before all files were correctly 
downloaded.

    

    That is correct.

    

      
 
Do I understand well that you reach recovery console?

    

    No. Just the recovery entries in the cold-start routine. They don't
    work.

    

      
From there as root

zypper lr

to see if you have mixed inadvertedly some repo that shout not be there.



      

        
or the earlier system shown in the boot selection. I expect I will have 
to reinstall,

however, I would like to try and copy off some files to a second 
(presently empty)

hard drive I installed a couple of months ago. If this is not feasible, 
I have a blank

hard drive that can be hooked up to a usb port if necessary. Am writing 
this from the

Windows os that came with the machine. I don't suppose there is anything 
in Windows


      

      
You can start the system on a life CD, branch the USB and if the HDD is 
sufficiently large do simply (on the empty and formatted usb disk naturally)
cp -ax /home  /pathtotheusb/
this will copy completely the /home so you can do a fresh install being sure 
you do not loose anything. 
Normally you should have /home on a separate partition (that you are asked at 
install. To see how your system is partitioned do in the recover root 
terminal:
lsblk
This shows you if the /home is separate.
If it is, you may choose expert mode in installing TW and tell to read in the 
previous mount points and the to format ONLY the root and evtl the swap. 
You will install and then restart.

    

    I am going to download an up-to-date edition of the system and

    start the machine using that. I will then see if there is a way to

    copy off the files I want to save. If that is not obvious, I will be

    back here. Am now writing on a Linux machine--Mageia--so I

    don't have to deal with Windows--I haven't actually used Windows 

    in at least 15 years, and I don't know how anymore.

    

    One note: problem is with a new machine, bought last June. It has

    a new-fangled solid-state drive that mounts (somehow) on the mobo.

    If it was an old drive, I would simply remove it and copy it on 

    another machine, like this one. 

    

      



      

        
that will do what I need--correct me if I'm wrong--so I can download a 
present version

of OpenSuse TW  or use a DVD that I downloaded last summer. Whichever is 
suggested,


      

      
Maybe thus a reinstall is not necessary all together. What graphic card did 
you use? If Nvidia, installed from their site or installed from rpm?

    

    FYI: graphics is in the CPU, no separate card.

    

      



      

        
I need instructions on how to recover important files and pictures and 
save them to

the second hard drive. (I have or will format that to ext4 from 
gparted.) Then I will

download a present iteration of the system and install it on the 
original drive.

Sorry about the double spacing--Windows T/B style!

Thank you for any assistance--doug



      

    

    Thanx again for answering. I'm going to d/l a new copy of

    TW now and proceed from there. I expect I'll be back here

    in an hour or two!
