When I turn on my laptop and press F2 to acces the bios it says password is clear but upon closing bios will not boot saying hard not availible. When i reboot the acer logo appears and the screen goes black, after several minutes a blue page appears with two options restart or advanced options, I open the advanced options and acces the bios by de UEFI and in the security options it says that my HDD Pasword Is Frozen. Other Passwords are clear. I cannot use recovery disks because drive is frozen. Computer is Acer Aspire E15 with Windows 8.1 installed on it and i can't BOOT with a cd-rom because it doesn't a cd player. Any help would be appreciated.
