/etc/grub.d/30_os-prober checks for the presence of os-prober with (or linux-boot-prober) using the 'which' command, but does not require which.
If you do a minimal install of F16 Beta TC1, os-prober and grub2 is installed but which is not, so 30_os-prober quits immediately because 'which os-prober' fails, and it never actually probes for other operating systems; so if you do a minimal Beta TC1 install alongside Windows, you get a bootloader with only Fedora in it.
grub2 should require which in order to resolve this issue.
Proposing as a release blocker as it partially affects the criterion "The installer must be able to install into free space alongside an existing clean single-partition Windows installation and either install a bootloader which can boot into the Windows installation, or leave the Windows bootloader untouched and working " (though this probably works okay with a full install, as the 'which' package likely winds up being present in a full install).
confirmed that if I customize package selection, add 'which' to the installed package set, and otherwise install exactly the same way, the bootloader menu includes a functional Windows entry.
os-prober is not installed on a default install from the 16 Beta TC1 DVD (in fact it's not on the DVD at all). Is this a network or some other kind of install?
I did a network minimal install. If it's not on the DVD that's probably another bug, but I believe grub2 is being adjust to require os-prober, so that should fix it: https://bugzilla.redhat.com/show_bug.cgi?id=734964

Discussed at 2011-09-02 NTH review meeting (as this is Beta, blocker status for final would be assessed later if it wasn't fixed for Beta). Agreed to accept as NTH, it would be good to fix this for Beta and the fix is simple.
