eMMC missing for OS boot

Hi,

I received my X4 today and I’ve hit an issue. I installed Windows Server 2022 , and everything went fine. After checking some things in the OS, I restarted the X4 and now it will no longer boot into windows claiming the storage is missing. I’ve checked the bios and the eMMC is still registered there. I’ve tried to reinstall windows with my original USB boot stick but when I get to selecting storage nothing shows up anymore. Any advice would be appreciated.

Hello BladeXyber, Can you make sure the EFI boot partition is installed on emmc?
Windows can boot first time and can not boot again, anything storage devices (SSD/USB) change between twice boot?
Since emmc show up in BIOS, this looks like more software issue not hardware issue. maybe you can check Windows10 or Linux see the issue still there?
