Hey guys, hope I'm posting in the right area and hope you can help. For the past couple of months I have been getting this error code when trying to start my laptop after or during a Windows update. It has been haunting my dreams. I have temporarily fixed it a few times now with system restore but that isn't working anymore. This left me so desperate that I tried to refresh my computer but am given this message "the drive where Windows is installed is locked. Unlock the drive and try again." Frustrated I said screw it and tried to do a whole reset and it says "unable to reset your pc. A required drive partition is missing." I searched Google and tried to find solutions and had no avail. I don't think my hard drive is screwed up because system restore has fixed this before but now is saying "to use system restore, you must specify which Windows installation to restore. Restart this computer, select an operating system and then select system restore" I hope I didn't screw anything up by trying command prompts that I saw on google when I typed in 0xc000021. Anyways I don't have a boot disk, I think there is one built in to my computer? Am I up the creek without a paddle or does anyone have any suggestions. I hope I put this in the right place. Thank you so so so so so much in advance guys.
