I have unsuccessfully tried to remove it in Safe mode and recovery console. After allowing chkdsk to finish, I still cannot remove this folder. Can i use the BESR recovery disk to boot the system and remove the folder?
It's certainly worth a try. After booting the system to the recovery disk, simply open a command prompt, browse to the file/folder you want to delete, and try the appropriate command (probably "del" or "rmdir").
