Have installed F17, overwriting Windows. F16 is on the same disk, different partition, and I need to boot into it for a while yet. But F16 does not appear on the GRUB menu installed by F17. From F17 I can access all files, but I still need to run some programs in F16 so need to boot into it. How can I teach GRUB that F16 exists? I enclose output of running "bootinfoscript". F17 is on sda1, F16 on sda6. Thanks for help.
