Yes I had the Bootcamp partition before updating Mountain Lion to Mavericks.
I ask because using Winclone 3.7 under Mavericks the Winclone Backup gets about halfway through then stops reporting some error or the other that I must admit I do not understand none of the report. Tried to copy and paste it here but cannot copy it.
I have checked the Bootcamp partition and can find nothing wrong with it and it still works.
