,After running Dell support assist this evening a new BIOS update was recc. I updated from AO7 to A09 (apparently released on the 30/06/15). However, after being prompted to reboot my system, after the update, the above error message appeared. So after selecting F12 to reset the boot options I could not set it to the harddrive so I selected "windows manager" instead and the system booted fine again. Just wondering if anyone else has come across this and also have I the boot options set to the correct setting. Any advice much appreciated.
Thank you
Karen
