Comment 200 for bug 477169

Meow81, the patch is the one mentioned in https://bugs.edge.launchpad.net/ubuntu/+source/grub2/+bug/477104/comments/77
Which in turns refers to this grub/trunk patch:

   Eliminate NTFS 4Gib barrier.

All I did was apply this patch to ubuntu grub, and regenerate wubildr. The reason you need to disable `insmod ntfs` is that the new wubildr will contain the updated grub ntfs driver which could be overridden by the old one on your disk, thus invalidating the patch.
