Hello,

I just installed Fedora on another partition on my HDD which also runs Windows 7, however, Fedora tried to install some updates,which failed, and now Windows 7 is no longer in my boot menu, and its been replaced by another build of Fedora in the boot menu titled "Schr?dinger?s Cat". I don't have any idea how this happened and I'm really worried I may have lost my Windows installation, but when I boot into Fedora and look at the other volume on my hard drive, all my Windows files are still there, and when I boot from the Windows 7 boot DVD it detects by installation on there. How do I fix this? PLEASE HELP!

Hi

Reinstall Grub2 on Fedora 20

You could reinstall grub by using either a Fedora 20 DVD or a netinstall image. 1. When the CD/DVD boots, choose Troubleshooting

  1. Go to Rescue a Fedora Installation from the menus presented. Once the system boots, the installation image should automatically mount your installation under /mnt/sysimage. Once that happens, all you have to do is run these commands
  2. chroot /mnt/sysimage

  3. grub2-mkconfig -o /boot/grub2/grub.cfg

  4. grub2-install /dev/sda This will install GRUB to master boot record. Also, ideally, when you run the first command, in the output, you should also see Windows 7 presented.
