Recently I played with bsdinstall and UEFI setup, which left the system unbootable (11.0-Release). The culprit is the MS-DOS volume lable "EFI " of the EFI partition. At least on Intel Single-Socket Servers (for Xeon E3 IvyBridge/BearToot + Haswell/RainbowPass), the UEFI firmware can't handle the identical path/volumelabel. Simply reformatting with a different volume label (EFIFAT e.g.) solves that problem! Shall I file a bug report? Btw, can someone explain in short words why BOOT64.EFI seems to be boot1.efi, but padded with 0x20 up to 128k? Thanks, -Harry
