i can install OMV 6 from an USB drive to an other USB drive. But when i try to boot then OMV my mainboards starts the UEFI every time. The UEFI recognizes the USB drive and its at first boot position - but doesn't boot. Secure boot is disabled. UEFI isn't in 'Bios Mode' (CSM). Is there a special setting to boot from USB drive when using UEFI? I had never problems with that on other mainboards.
Installing OMV 6 on a normal 2,5'' HDD works and i can boot from the HDD.
i tried this from USB2.0 and USB3.0 ports. all the same.
