partition layout:

Part    Start LBA       End LBA         Name
        Attributes
        Type GUID
        Partition GUID
  1     0x00000022      0x00000821      "loader1"
        attrs:  0x0000000000000000
        type:   5b193300-fc78-40cd-8002-e86c45580b47
        guid:   cbcbef44-e627-42bc-b134-93b6f3784b8c

        attrs:  0x0000000000000000
        type:   2e54b353-1271-4842-806f-e436d6af6985
