Ubuntu 16.04 LTS was damaged during an upgrade and it can't be fixed. I need to save all my files in the disk in another disk.

When I log in as root during recovery mode, I see all my files there and I can read them without issue.

However when I connect a new disk (usb or hard disk) via USB this is not visible in the media folder, therefore I have no way to copy the files somewhere else, what should be done so that I can connect an external disk and copy all the contents that I need into the other disk?

    did you mount the drive? I don't believe that recovery mode will automount – ravery Dec 16 '17 at 17:10

    The linked question addresses your immediate issue, though I believe that you will have an easier time with either a live Ubuntu system that allows file system through the familiar graphical user interface or a re-installation “without formatting /home, as well as without any old config files”. – David Foerster Dec 16 '17 at 18:57
  • @ravery and others, this was the right tip. Once I mounted the disk I needed, I had to make the file system writable with mount -o remount,rw / as in recovery mode it is read-only, I am now in the process of copying over the documents and all seems to be going in the right direction, many thanks! – NetNeutrality Dec 16 '17 at 20:48

Try the following to mount an external in recovery mode:

  1. Plugin the external HDD, then run sudo fdisk -l to know the partition information.

  2. Create a mount point:

    sudo mkdir /mnt/usb
  3. Now mount it at the location in step 2:

    sudo mount -t <file_type> /dev/sdb1 /mnt/usb -o umask=000
  4. Now you should be able to move the files over.


  • /dev/sdb1 is imaginary yours could be /dev/sdc1
  • umask=000 makes it writable




use a live installation cd boot it then copy all the contents from your bricked ubuntu system to pendrive easy
