Bug#693674: Wheezy DI-b3 amd64 GRUB overlooks Win7



Thanks for your reply -- for some reason it didn't arrive here as email,
but I found it tonight while looking in the debian-boot list archives.

Yes, exactly.  The mention of black arts also makes me hesitant to interfere
when the automatic process gets it wrong.  The GRUB ecosystem seems more
complicated, the more I try to understand it, with the various scripts
which probe and update and install, but aren't really discussed in the
mainline grub documentation sources, such as they are.  Perhaps in section
6.3.6.2 where it says "See the grub manual for complete information."
there could be some hyperlink[s].

It's too bad the ISO doesn't provide a way to boot into the completed
installation, without overwriting the disk's MBR.  I would be more
confident to experiment with GRUB configurations and probing if I could
see what it was trying to install before I commit to it.  I don't want
to lose the ability to boot the existing Win7 system on my wife's computer.

: you can reinstall GRUB and get a shell to use 'update-grub'.

I see that the beta-4 version is available today.  I'll grab that, and try
it out to see if it will work automatically.
