Hello, I am new in the forum. I have been using Zorin for a long time, but just joined this site. I never had a problem with Zorin and that is great. However, this is the first time I have an issue and I think it is going to be minor. I do not have enough experience and that is what brought me here.
I have an old version of Zorin installed on a Lenovo X220. I wanted to try Zorin 16.2 via live USB. I went through the installation options but did not start the installation process. I shut down my laptop and removed the installation media, to return to my previous OS to backup some files and I got the error
pxe-e61 media test failure check cable
Note that I just changed the boot order in the BIOS and as I said, I did not start the installation when I was running the live USB. I tried resetting to the default configuration in the BIOS but the error persisted. Also, my hard disk is not failing because I am able to browse it through my live USB. I have read other similar questions but my case is different, because in most cases this happens after installation, and not by just running the live USB. Please help me. I need my previous OS working so I can backup my files before installation. Finally, I tried doing a backup with my live USB and Deja Dup but most of the files do not get backed up. It shows permission denied. Thanks in advance.
I'm not sure what this error is, but searching online it seems this refers to an error trying to boot from a media over the network. Make sure the boot order does not check for any network devices before the hard drive i.e., plugged through ethernet cable.
My previous OS is Zorin 12.4.
I tried clearing CMOS through the BIOS but it is still trying to boot from the network. I even removed the network device (with "!") from the boot order, with no luck.
I think you can help me in two ways. By fixing the boot problem or by finding a way to do a backup of my files. If I can back up my files there is no need to return to my previous OS. I tried to back up with Deja Dup, but most of the files do not get backed up, apparently by permissions problems. I am trying to back up my home folder.
Is there a way to back up through the Live USB with any back up software? Since Deja Dup is not working properly, I tried to install Vorta but there is no space available. It seems that it cannot be installed when you are running the OS with a Live USB.
It looks for a networked drive when it cannot find your physical harddrive. If you adjusted your boot order and the error is still occurring, then it likely means that your hard drive is not being recognized.
I cannot fathom a way that running a LiveUSb would suddenly turn your hard drive invisible. It may just be the funny timing of things that an error on your hard drive appeared right when you booted something else.
If you can boot back into the LiveUSB, you may be able to use the disk management tools such as Gnome-Disks or Gparted to examine your hard drive or test it.
Backing up the drive:
If you can access the drive using LiveUSB or by removing the drive and plugging it into another machine, I would actually recommend against using a GUI backUp creator like Timeshift or DejaDup.
If your edition is 12.4 and you are moving to 16.3, that is quite a leap. Trying to solve Software from two editions back will be problematic. It really is personal files and data that gets priority for your needs. Even your home .config directory can be ignored since many of those configurations won't match the standards on 16.3 from 12.4
I would just go through the HOME directory and start with your desktop or documents folder and look through what you want to keep. If you want to keep everything, right click your ~/Documents directory and choose to Compress the file. You can compress it as tar.gz. Compression of a large directory can take a long time. But it would take just as long if not longer using a GUI backup tool - since compressing it is the first thing that it does, too. They usually then add their own markers or encrypt it...
Repeat this for Pictures, Videos, etc.
Make sure you reveal hidden files and look through your home non-hidden and hidden files. For example, since I use launchpad, I would save a copy of dput.cf from my home directory. You may have similar files. If not then, you are in the clear.
You may want to keep a copy of bash-history or wget-hsts.
You won't need to save copies of your bashrc or your xsession or .profile.
OK, thanks for all your suggestions. But what can I do with the files that show permission denied? For example, some PDFs have this restriction. I cannot backup or open them. Before this problem happened, I could access them with no problems.
So I found that by login as root from the terminal, I was able to open the files that previously showed permission denied. Then, I created a back up with Deja Dup, closed the Deja Dup GUI and started the back up from the terminal with sudo deja-dup --backup, to make sure that it had root privileges. But I got the following error.
Failed with an unknown error.

Please help. I am definitely running out of options.
You were right. It seems that my hard drive is damaged. Somehow this happened when I was running the Live USB, so I thought that I ruined something when I was going through the installation options. But I actually did not change anything. It was merely a coincidence that the hard drive failed at that moment.
I realized this when I tried to open the files that had the read and file shrank errors. They are damaged both in the source as in the backup destination. I cannot open them. I checked the damaged partition with GParted and had no errors, but it took less than a second to do the check, so I wonder if it actually did something.
However, the command badblocks found 22252 damaged blocks so it is more likely that the disk is actually damaged. Now I regret myself for not doing periodical backups. I lost some of my files. Anyway, is there something I could do to repair the damaged sections and recover them? Thanks for all the help.
This is unlikely. Repairing is not so straightforward.
If there is physical damage to a disk - there is no repair. I would simply move the Good Files you want to keep to another drive manually. Then, if you feel inclined, you can try using DiskDigger to try to recovery data.
The Free version will gather everything as Unlabeled data. Sorting it out is nightmarish. So I learned to run it for One File Type at a time. Such as run it for just .docx then run for just .jpg - and so on.
