I have and it was fine. I recommend that you back up your bootcamp partition with WinClone. Its well worth the price, and saved my bacon a number of times.

Does this mean you needed to restore BootCamp this time, due to updating to Yosemite ?
 
I installed all of the public betas and the final release and my Bootcamp partition was completely unaffected.

Good to know, thanks for the info. I had 3 partitions on the hard drive ( OS X, BootCamp Windows 7 and BootCamp Windows 10 - Technical Preview ) and the Yosemite installation did not work "out of the box".

However, by having 3 partitions I did not have the recovery partition and it seems to me that Yosemite did not install because of this.
