I used the feature "Protect drive from boot" of Bitdefender. It made me couldn't use features of MS like Refresh, Reset with error "The drive is locked, unlock the drive..." 2 times. First time, I must use backup of AOMEI. Next time, I couldn't use any thing to recover my PC, Hirent's boot, AOMEI, Refresh, Reset..., then I tried to reinstall Windows( 3 times) -> No operating system, I tried to install Windows on another HDD, it worked, then I deleted the whole drive with Paragon Partition then rebuild the MBR, and now it work just like the old time. Now I'm using Avira Pro.
