Comment 52 for bug 610898

Did a fresh maverick install and then upgrade to Natty on a non-Windows partition. No prompt on where to install grub, and it updated wubildr correctly. After booting into Natty I could run "grub-install" and it correctly updated wubildr on the windows partition without any prompts and did not allow install to the drive MBR.

The following showed my tests :
bcbc@ubuntu:~$ mount | grep '/host'
/dev/sda3 on /host type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
bcbc@ubuntu:~$ sudo grub-install /dev/sda2
Installation finished. No error reported.
bcbc@ubuntu:~$ mount | grep /dev/sda2
bcbc@ubuntu:~$ sudo mount /dev/sda2 /mnt
bcbc@ubuntu:~$ ls -l /mnt/wubildr
