I have a Dell Inspiron 5521 laptop running Ubuntu 15.10 and Windows 8.1 on dual boot. I was moving some files in the terminal when i did sudo mv /* to an external SD card. I immediately realized that I made a mistake and cancelled the operation and in panic, I powered my system off. Now the system will not boot, it shows a Checking Media [Fail] messages. I checked the BIOS settings and te boot options are empty.
I then loaded the boot-repair disk and it showed everything as normal but gave the following message when I used the "Fix common issues" option.
GPT detected. Please create a BIOS-boot partition (>1MB, unformatted filesystem, bios_grub flag) This can be performed using tools such as Gparted. Then try again.
The output of ls -lah on the SD card is: output of ls -lah on SD card:

Please help. This has been driving me crazy.
Edit: I tried Reinstalling Ubuntu from the live disk, it was going ok unity I encountered the error: The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot
. I am not sure why this error would occur.
mv /* /media/username/sdcard
, something like that,right ? I'd say reinstall, overwrite your Ubuntu partition with new Ubuntu partition. It's going to be the easiest solution to repair the system. Ifmv
didn't get as far as yourhome
directory, you could still recover those files with a bootable USB drive and USB disk to save files there. But simplest , less painful solution - erase the old stuff with new stuff. – Sergiy Kolodyazhnyy Jan 07 '16 at 04:27ubuntu@ubuntu:/media/ubuntu/a7089b2c-2748-4b9d-8f17-02169bb0402a/nitin$ cp 2_node_addition.png /media/ubuntu/SETTINGS cp: cannot create regular file ‘/media/ubuntu/SETTINGS/2_node_addition.png’: Permission denied

and your files are owned by your original username. What you need to do is usechroot
which basically is using system on hard-drive through live usb, sort of connecting to it. Follow the chroot instructions , then connect another usb disk, mount it (easiest withudisksctl mount -b /dev/sdX
, find out X number withlsblk
), and then copy your files from home to usb. After all done, wipe that partition and install new ubuntu partition – Sergiy Kolodyazhnyy Jan 07 '16 at 05:35
