[Bug 813387] [NEW] Ubiquity allows to install GRUB into Windows partition (dangerous and useless option)

[YannUbuntu]

Public bug reported:

Bug confirmed on all Ubuntu versions until Natty.

In the "manual partitionning" menu, Ubiquity allows to install GRUB inside any disk and any partition.
If a beginner installs by mistake GRUB inside a Windows system partition, it has only bad consequences :
1) GRUB won't work as it needs a chainloader
2) If the user is been told to reinstall GRUB in the MBR: since NTFS partitions are case insensitive GRUB will not be able to detect Windows. ( http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Core_On_Windows )

I suggest Ubiquity should only propose to install GRUB inside:
- any disk
- the partition of the new Ubuntu being installed (for chainloader users)
