In which case it should install grub with a pre-awareness of other OSes present. Of course, one day an upgrade will be done, update-grub will be run without os-prober, and any other OS will disappear... that sounds like something Microsoft would do. Surely during installation, a check for other OSes should be performed, and if any are found then os-prober should be installed *and* *enabled* by default, as it will be needed during every subsequent update-grub. My sid just had its os-prober disabled by an 'upgrade', and I needed to tweak the grub defaults to get it back. Linux used to be promoted on the basis that it could be installed in a Windows system for evaluation if there was enough spare drive space, without affecting the Windows installation. It's hardly reasonable to expect a newcomer to Linux, having apparently lost his Windows installation, to research and install os-prober to get it back. The most clueful will simply run a Windows boot repair and forget about 'that damned Linux'. -- Joe
