Hallo zusammen,
lustigerweise habe ich ein ähnliches Problem. Habe vorgestern mein W8 runtergelöscht (da meine Platte nur noch am arbeiten war und hab W7 nun droben - vermute das die PLatte ggf. auch etwas kaputt ist aber eine neue ist auf dem Weg).
Nichts desto trotz findet meine Grubinstallation keine Ubuntuinstallation mehr. Auch mit der Option --force hatte ich keinen Erfolg erzielt.
Kurz zu meinem System und danach mein Vorgehen:
SYSTEM
sda: Platte mit W7 (war damals auch der Bootloader droben)
sdb: Platte mit Ubuntu, partitioniert mit sdb1 "/" und sdb5 "/home"
sdc: USB Stick
