I cannot get dual boot running with ubuntu 12.10 and windows 7. I spent
a lot of time trying to get it work, without success. With boot repair,
I get either windows 7 running by repairing MBR, or ubuntu 12.10 by
reinstalling grub. But I cannot start windows 7 after grub install, I
get always "Invalid Signature".

Boot repair: http://paste.ubuntu.com/1311856/

I get also this warning:
grub-pc (2.00-7ubuntu11) wird eingerichtet ...
Creating config file /etc/default/grub with new version
/usr/sbin/grub-bios-setup: Warnung: Dieses LDM hat keine Einbettungspartition, 
Einbettung würde unmöglich sein.
/usr/sbin/grub-bios-setup: Warnung: Einbettung ist nicht möglich. GRUB kann in 
dieser Konfiguration nur mittels Blocklisten installiert werden. Blocklisten 
sind allerdings UNZUVERLÄSSIG und deren Verwendung wird daher nicht empfohlen..

Also compared to grub 1.99, the win7 partition needs to be be mounted in
order for grub 2 os-prober to detect it. update-grub does not detect
win7 when partition is not mounted, this was different with 1.99.

Also update-grub always produces an error:
Linux-Abbild gefunden: /boot/vmlinuz-3.5.0-17-generic
initrd-Abbild gefunden: /boot/initrd.img-3.5.0-17-generic
Windows 7 (loader) auf /dev/sda1 gefunden
/usr/sbin/grub-probe: Fehler: Unbekanntes Dateisystem. (Error: Unknown 
Filesystem)

Can you please tell me how to downgrade to grub 1.99 on ubuntu 12.10?
