I am having trouble after a normal restart of my Asus laptop. The scenario is this; after a normal restart, my computer went into some sort of automatic repair mode which eventually led me to a blue screen and error code 0xc00021a. I have viewed many fix videos and been led to using the command prompt screen. My issue is this, when I type c: into the prompt, I am given this response "The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted" This is extremely frustrating because there was literally nothing wrong with my computer prior to the restart. Any help would be GREATLY appreciated!
