Hi all! I am using a fleet of UDOOs in a headless manner and, upon provisioning, I update the BIOS boot settings to switch over to "Legacy" boot to avoid ever booting into the EFI shell (as well as disabling the Arduino). However, I have found that sometimes an UDOO will end up booting into that EFI shell regardless and upon inspection, the BIOS setting was switched back over to Dual Boot (as was the Arduino setting). This is a pain since it requires a monitor and keyboard to fix and the UDOO is not in the most accessible location. Does anyone have any ideas what could be causing that setting to reset? The RTC battery status reports "okay" and the UDOO is not physically touched (no jumper pin was moved) when the issue occurs. Any help would be appreciated! Thanks!
It seems like this may be a similar issue? https://www.udoo.org/forum/threads/udoo-x86-emmc-not-booting-on-uefi-mode.33553/ In my case as well, even though it prioritizes the EFI shell, the OS is still available as a boot option if you check the BIOS boot order. The EFI shell is simply the higher priority
If you are getting this kind of problem, you should start with your bios settings and check your hard disk's contacts inside your PC.
Awesome and interesting article. Great things you’ve always shared with us. Thanks. Just continue composing this kind of post.
