Bug#496981: win32-loader fails if a directory already exists who's name matches debian in windows case insenstive matching but not in grubs matching (Which I presume is case sensive)
justification: renders the package unusable for some users.
according to firstname.lastname@example.org win32-loader will use an
existing directory that matches debian in the windows filesystem.
Unfortunately grub's filename matching and windows are different leading
to grub failing to find the files.
I am filing a bug to track this issue
