ok so, I followed what u said, I plug in the usb key and try to restore the OS, but when it started to restore I saw that it was restoring into same HDD not in mSATA SSD. So when i canceled it then it normally rebooted into windows, everything was running perfect just like before, but when I open the my computer, my second hard drive was not showing there. Even the intel rapid storage tech and BIOS is showing that hard drive is there and running but its not showing in My Computer. plz help me
