I have Fedora 15 (x86 64 bit) and Windows 7 running on dual boot system. Although sharing a mbr, the installations reside on different physical disks. Because I was NOT smart and did not preupgrade, I simply popped in the burned iso and selected the upgrade option. When It asked me if I wanted to update grub, I said "no" since grub seemed to be working fine and why mess with something that works (I did not know grub2 was part of the upgrade). Everything installs fine. When I reboot, the old grub screen comes up and .. only shows me the option to boot into Windows. I did some digging around and it seems most people have the opposite issue (new kernel but no Windows boot option). I booted into rescue mode and looked at the boot partition. In the grub directory, I have a brand new grub.conf with only a Windows option and in grub2.conf I have an empty file. Now, the question is how do I repair grub.conf so it boots the new kernel? Do I have to reinstall again and this time select update grub? If so, how do I make sure it does not nuke the Windows option.
