My laptop freezed, so I restarted my system manually, and ended with the Grub terminal. I tried running the ls command in Grub terminal and got the result as
grub> ls
(hd0) (hd0, gpt2) (hd0,gpt) error: failure reading sector 0x100800 from 'hd0'.
error: failure reading sector 0x100800 from 'hd0'.
I am unsure whether the OS crashed or some problem with my SDD. Can someone help me on that ?
