I'm trying to install OMV on a Intel Celeron N3450-based mini-pc from Beelink. The system comes preinstalled with Windows 10 and boots using UEFI and the Windows bootmanager.
I've followed the instructions on this site and used Etcher to created a USB stick from the openmediavault_3.0.94-amd64.iso.
However, I've found to way to actually boot from this usb stick. Even manually changing the boot devices in the bios to all sorts of usb-devices didn't work.
