Hello, I have been having a problem with my laptop for the past week where I cannot start it up due to an error called "UNMOUNTABLE_BOOT_VOLUME". It gets stuck at the starting windows screen with no load bar. Then after a few minutes it will switch to a blue screen with the error. I tried going into safe mode but that also gave me the same result. Safe mode will fail when it hits this file "\windows\Systems32\Drivers\aswRvrt.sys". My Laptop is a Samsung laptop with Intel core i7 and it uses windows 7. I would also like to mention that I did not download any new software recently that I'm aware of. Any help would be appreciated.
