Win7 can't be loaded after installing ubuntu 11.10

Question

I use MacBookPro8,2. First of all I installed MacOS, then WIn7 on sde4, then Ubuntu on sde5 and swop on sde5. After installing ubuntu win7 isn't loaded when I choose it in grub. Win boot writes the following message: file: \boot\BCD Status: 0xc0000225 An error occurred while attempting to load the boot configuration data What shall I do? Try to repair windows using CD(in this case I think I will damage grub) or I can somehow configure grub to make it work properly?
