when starting up on my acer aspire x3200 it goes to the erecovery management with the option for restore system from factory default and restore system from user back up greyed out and all i can chose is the exit button that restarts the computer and puts me back on the erecovery management. i have tryed to boot from windows disk but when doing a clean installion it says windows cant not install files files may be corrupt or missing error code 0x80070017
