Before the last shutdown of Ubuntu 20.04 my storage space of disk was very low, then after starting my laptop this error occurs.

Error: no partition found
Cannot read or write outside partition

When I enter into the command line by pressing the c key grub> loads, but on giving commands like ls, cd, sudo, etc. it says error: can't find command...

After pressing the power button, the first thing that comes to the screen is error: no such partition, four times the same sentence is repeated, and at the end Press any key to continue On pressing any key, some options appear.

  • Ubuntu
  • Advanced options for Ubuntu
  • Memory test

but all results to reload the boot but no results. On restarting sometimes this kernel panic screen also appears.

enter image description here

Another time it goes until ubuntu logo appears after which login field to appear but after logo, immediately black screen appears saying

/dev/sda4: clean, 1500298/7749632 files, 29454730/30995712 blocks

And nothing happens, until I press power button and it shutdowns

  • I would boot a live system (eg. Ubuntu install media) and do a file system check (ie. fsck). If errors are detected & fixed, I'd expect your system to boot normally next login. – guiverc Dec 27 '20 at 06:33
  • Oky, thanks. I will give it a try and inform you the outcome – analogbeing Dec 27 '20 at 06:48
  • Found that, that was due to low storage. I use Ubuntu live usb to free up storage and now its working – analogbeing Dec 27 '20 at 17:03
  • That may be, but in my case I found an easy solution. I just make the usb bootable and load the ubuntu live, the mount my disk /dev/sda4 into /mnt and delete some stuff to clear up some storage. This worked for me – analogbeing Dec 28 '20 at 06:44

The error was due to low storage, after access the machine via live Ubuntu usb freed up some storage and now its working.
