Today, I update 7760 with BIOS v1.10.1. First, I download and excute .exe file, but get error message "Unable to lauch UI module". Then, I download and save .rcv file into a USB key and perform following steps, shutdown, unplug the power cable, press ESC and Ctrl simultaneously, plug the power cable and release ESC and Ctrl. After update BIOS and reboot the machine, it can not boot windows 10. In boot sequence memu, only NIC and httpsBoot remain. I add Windwos Boot Manager manually, and reboot, still can not boot windows 10. The newly added Windwos Boot Manager missed. [IMAGE][IMAGE][IMAGE][IMAGE]
