Bootcamp gone after updating to DP4

[scenox]

Hi,

after updating to DP4 (it might also be DP3), I can't boot into windows bootcamp partition anymore. The bootcamp partition is still here, but it seems it's not bootable any more; it's not recognized by start volume. Has anyone a solution for this problem without reinstalling windows?
I've tried repairing with disc utility, but it says it isn't able to repair the partition.
