I have an Acer Aspire ES1-512, x64-based PC laptop running Windows 10 with BIOS Version Insyde Corp. V1.07.
When I tried to boot, it said, "No Bootable Device". When I used my Recovery USB, it will not Recover saying, "Your hard drive is locked, unlock your hard drive and try again." I have no idea how to "unlock" my hard drive. I had a similar problem 6 months ago, and when I ran partdisk, the drives were all visible, I just couldn't access (unlock) the hard drive. I did so many different things, I don't know what really brought it around again. THIS time partdisk shows only the DVD drive and the Recovery USB drive, but NO hard drive.
I reset BIOS to its factory defaults, and it shows the hard drive in the boot portion.
HELP! If you can't help, do you know where to go to get to it?
