If you are used another partitioner, like me, I used linux to get rid of that 100MByte windows partition, and installed linux next onto another HDD, I needed to pull of the cables from the linux HDD and then using only the Win7 HDD I can install Win7 SP1. I hope it's a solution for your problem.

If you still can't install it, or the linux is on the same drive, I think there's no solution. Only to re-partition the whole HDD and use Win7 partitioner.

Fix: The Windows 7 partition must be the Active Partition.
