Sorry, I will elaborate:
- you said that (of course) certain files should be present for os-prober to
find the operation system
- that makes me realise that I always manually installed ntfs-3g, and I
installed not too long ago the latest 'advanced release' (= 2010.3.6AR2)
- thus, I first reinstalled ntfs-3g from the repo's (2009.4.4). Running
'os-prober' after this shows W7 again
- I installed the latest ntfs-3g 'non-advanced' (2010.3.6) (as the newer
ntfs-3g drivers provide a lot of speed improvements and provide bug fixes).
Again, running os-prober showed W7.
- To be sure, I reinstalled the advanced release and as I expected, W7 did
not show up.

Above steps lead me to the conclusion that ntfs-3g is the broken part on my
computer.

Below is the changelog for the 2010.3.6AR2 release (
http://pagesperso-orange.fr/b.andre/changelog.html):

   - developped "lowntfs-3g", a driver variant using the fuse low-level
   interface
   - fixed a compilation issue with uClibc
   - fixed modifying the read-only flag on a directory
   - fixed bad error checking when closing a compressed file
   - concealed files marked as "hidden" unless option show_hid_files is set
   - marked files whose name has a dot initial as "hidden" if option
   hide_dot_files is set
   - redefined a default user mapping (a few changes in mount options)
   - enabled case insensitive file names
   - fixed a bug in ACL inheritance

I can imagine that either the case sensitive file names or the changes to
hidden files make os-prober fail. This topic on the forums of Tuxera could
be of help:

On my W7 partition, I have (with these capitals) and with ntfs-3g 2010.3.6:
/Boot/BCD (see attachment)
/bootmgr

With 2010.3.6AR2, no Boot directory is shown and also /bootmgr is not
available (also if I enable 'show hidden files' in Nautilus).

If you ahve more questions, please ask. and feel free to set the status to
whatever you think is appropriate.
