Comment 7 for bug 1561842

Just checking my email this AM and reading your recent replies to Ubuntu GNOME mailing list i see you included a boot info summary with both the Windows drive and the Ubuntu drive connected:

The output of parted -l shows Win 7 is installed non-EFI but Ubuntu is installed in UEFI mode:

That is, in itself, problematic. So please open a new thread at Ubuntu Forums here:

One of the forum mods there uses the moniker oldfred and he'll be able to answer your question and help you get that straightened out. My method would be to back up all the data on the Ubuntu drive and reinstall in non-EFI mode after creating a new msdos partition table on the Ubuntu drive, but there may be a simpler way :^)

Please do be patient and wait for oldfred to reply.
