this is directly related to another post from earlier today but is is a sifferent question. i hope that this new thread is appropriate. i have a compaq and it runs with Unified Extensible Firmware Interface (UEFI). when you start the computer and go to Startup Menu one of the options is f11-system recovery. from this menu you are supposed to be able to access options including: computer checkup, microsoft system restore, file backup, and system recovery. you are suppose to have these options even if your system can't boot to windows. well, no matter what i try i cannot get to these options. it just brings me to a black screen that says error loading operating system. i need to know why this is happening and why i don't even have an option to start in safe mode. please hold me, tell me everything will be ok, and help me fix this.
