Unfortunately your disk C: is recognized as MBR partition, and error is:
2014-03-23T18:04:16.448+08:00 [07940 info 'Default'] Cannot mix MBR and GPT partitions, partition 0 is GPT!
2014-03-23T18:04:16.448+08:00 [07940 info 'Default'] Failed to create the partition Tables error:-1
but mixed GPT/MBR configurations are not supported.. the dual boot configurations are not supported too.
You can try to exclude second disk (BOOTCAMP) from conversion and try again.
