i had some kind of file system error in my kali linux system. after like two weeks, i figured out how to fix the problem using manual fsck /dev/dm-0. it was booting into inftrms or something like that (command line) well i did the manual file system repair and after that it worked. however, it wouldnt let me use metasploit or alot of my programs. i think i trashed some of the file system or something. so i was messing with some kind of partition util, saw a filesystem that wasnt mounted, and then mounted it, thinking , hey maybe thats why its not working. well now it boots into command, can someone please help me

Hi and welcome to the forum.

You appear to be new to Linux generally, you may want to have a look here for some tips on the details you should include in your question, and here for some advice as to whether there aren't better distributions to use while you're learning.

I'd also advise you to install something other than Kali. It's not a suitable distro for novices.
