Fedora 17 and grub2...While installing fedora 17 from the live cd at the end of finishing the installations i got an error like "installing bootloader failed ..system any not boot properly " the problem was maily with grub2 version .Even though the grub2 is much better than the older one it has some bugs .it shows some problem whiling installing to a system with older grub.
We can try reinstall the grub with the distro dvd rescue mode...
the root file system will be loaded to /mnt/image
2. grub2-install /dev/sda
installing the grub to ur harddisk ..in normal mode this wont work we should also give --force and --recheck
grub2-install --force --recheck /dev/sda
3.to get all the operating system use
grub2-mkconfig -o /boot/grub2/grub.cfg
the -o will create the config file
