Grub2 (aka grub_pc) is very (in my opinion too) picky in where it agrees
to be installed into. If my memory serves correctly, the old grub
(grub-legacy) could be installed, for example, into an extended
partition, and control passed to it from a Windows bootloader which in
turn was booted from the Windows MBR. This let me leave the MBR, with
special features to access Windows recovery partitions, intact.
With grub-pc, I never found a combination which worked this way. I have
now developed a workaround for dual-boot systems, but I generally regard
grub2 as too restrictive for implementing "creative" boot strategies.
Maybe there are good reasons for it to work like this, I do not know...
Thus my suggestion is to try to use the old grub instead.
