Summary:The embodiment of the invention provides an operating system starting method and device, an electronic device and a storage medium, and relates to the technical field of computers. The method comprises the following steps of running a firmware; reading a pre-stored target variable through the firmware; when the first PCI scanning is carried out through the firmware, taking a target controller indicated by the target variable as the first position to carry out scanning; transmitting the identification information of the target controller to a kernel to be started through firmware; loading and starting a kernel of a target hard disk corresponding to the target controller through the firmware; and starting an operating system of the target hard disk through the kernel according to the identification information. According to the present invention, the firmware can obtain the controller information of the target hard disk required by the user through the target variable, and then the kernel of the target hard dis
