I am using an X10DAL-I motherboard and a PCI-E NVMe SSD. I am aware that I need to install the OS in UEFI mode and have made the Bios changes; However, when I invoke the boot menu to select UEFI USB flash drive which contains my OS, it is not listed as an option. I have also checked the Bios UEFI boot options and it is not listed. How do I get the motherboard to see my UEFI USB installation devices.
Please check the file system and make sure that it is not MBR or NFS. Please make sure the USB is using GPT and FAT32. This should resolve the issue. If you are still having the issue even when using GPT and FAT32, please contact technical support for further troubleshooting of the issue.
