So, I booted up my computer a few days ago and what came up was an error message saying "Failure to mount filesystem". Now when I try to boot up from the HDD the word GRUB comes up over the entire screen and the bottom right keeps flashing as if it is writing GRUB over and over again. My father thinks the loader might be broken but we cannot figure out how to fix this problem.
