Wenn ich den Computer einschalte, kann ich GRUB sehen und Ubuntu booten. Aber ich kann Windows nicht booten, weil ich es nicht im GRUB sehe.
Ich habe sowohl Boot-Repair als auch sudo update-grub ausprobiert umsonst. Es ist wahrscheinlich erwähnenswert, dass das BIOS UEFI verwendet, um das Booten zu verwalten.
Ich habe Ubuntu 12.10 und Windows 7 irgendwo auf demselben Laufwerk installiert.
Warum befindet sich der MBR auf /dev/sdb?
Dies ist die Ausgabe von bootinfoscript:

Akzeptierte Antwort:
Führen Sie einfach sudo update-grub aus und sudo update-initramfs -u .
Und es sollte erledigt sein.
Falls sich Ihr Windows auf /dev/sda1 befindet das sudo update-grub Befehl sollte Windows 7 (loader) auf /dev/sda1 gefunden enthalten (Deutsche Lokalisierung)
