Hi Bruce.
Thank you so much for your quick reply.
The board version is “ODYSSEY - X86J4105800 Most expandable Win10 Mini PC (Linux and Arduino Core) with 8GB RAM : Unactivated version without eMMC”.
Do you mean that the board will be automatically rebooted by itself several times without pushing the power button by a user ? According to “https://wiki.seeedstudio.com/ODYSSEY-X86J4105-Installing-OS/”, the user needs to push the power button after BIOS upgrade.
“When the BIOS is upgraded, reboot the ODYSSEY - X86J4105(Switch on and off the power).
The first boot up from the BIOS upgrade is relatively long , please be patient to wait, and the installed OS will launch eventually. It will take around 3 ~ 5 minutes”.
I pushed the power button of the board after BIOS upgrade to power off and on again and had waited for over 5 minutes but it wasn’t booting up. Since this board version does not have an eMMC, I assembled Samsung 970 Evo Plus 1TB SSD into the board before BIOS upgrade and disabled eMMC in BIOS. Can it be affected to this problem ?
