I’ve made a Windows 10 boot USB successfully. In your BIOS you’ll see two partitions—USB and UEFI. Which one to pick depends on your setup. For a system with an ASRock Z87M Pro4, i5 4670K, and 4x4 DDR3 1333 RAM, the USB partition is typically recommended for booting. If you need more details, let me know!
You cannot view partitions through the BIOS settings. It seems you're referring to a boot menu offering UEFI or legacy options—use UEFI if available.
You might want to consider both options, but UEFI seems to be the stronger choice.
