im having problems with my hard drive on startup, it says somethings wrong with windows. it says i need to run checkdisk on drive F and try uninstalling the drivers. but the thing is it doesnt let me get into windows to run checkdisk, i cant even get into safe mode. the error comes up before i can react to anything. do any of you know what this problem is? and how to fix it? all info would really be appreciated, thank you
