I've had similar issues with factory installs of 64 bit Vista, here's
a trick I've used successfully in the past.  Try using the Windows
tools to resize the main partition, they should be included with a
standard install.  Once free space is made open, install your os and
boot loader to the new *nix partition and use the Windows bootloader
to daisychain to grub and boot away!

Hope this helps,
Chris from Kearney
