Yes. The Windows bootloader that it puts in the MBR just looks for the first 
"bootable" partition and loads the bootloader from the start of that 
partition. On the other hand, if grub is installed in the MBR, it uses its 
configuration file to decide what to do and completely ignores the "bootable" 
flags on the partition table entries.

At least that's my understanding.
