Since there is no GreenScreen just an error message there might not be an Craslog?? and as Ev0 writes its pretty self explaining "No media/hdd .......... could be found"
So problem is, there is no HDD in the path or HDD is bad, maybe a mount problem so please check your mountpoints
by pressing BlueButton>>BlueBotton>>choose device manager from menu and check if you have any HDD mounted.
If you have no HDD but one UsbMemorystick mounted as HDD it could be that this mountpoint is lost and you have to re mount your storage device
and in Backup Manager choose the correct storage device for backup image location.
