sysctl machdep.bootmethod will tell you. It is completely unrelated to GPT vs. MBR, NetBSD can work with GPT both on BIOS and UEFI booting machines. The installer (w/o asking the user) always picks the method it was booted itself. If UEFI, you will have an additional partiton (the "ESP" aka Efi System Partition) with msdos file system. This is where the UEFI bootloader binaries live. Martin
