Question
Open boot device failed.
I am using FortiGate 200. One day I got the problem of the FortiGate and I rebooted it. After rebooted, the whole box cannot boot up again. When using console for checking, I found that the box cannot boot up successfully, there is the error log " Open boot device failed." I go into the configuration menu, and tried " Format boot device" and " Get firmware image from TFTP server." , however, I failed to upload the firmware to the box successfully. I got the following error message during the upload via TFTP: " Verifying the integrity of the firmware image." " incomplete distance tree" Do anyone know what it means? I tried many firmware version such as 2.30, 2.36, 2.50MR1,2,8 but all failed. Gary
