Fedora 20

Multi-boot Manual Bootloader
Fedora 20 does not offer an option to install the bootloader to a partition. This is the workaround:


 * 1) Begin Fedora installation as usual.
 * 2) Enter the Installation Destination spoke.
 * 3) Click on Full disk summary and bootloader… at the bottom left
 * 4) Select the disk with a check and click Do not install bootloader
 * 5) Click Close, and proceed with installation as desired
 * 6) When installation is complete and Fedora tells you to reboot, don’t! Instead hit ctrl-alt-f2, and run the following commands:

chroot /mnt/sysimage echo "GRUB_DISABLE_OS_PROBER=true" >> /etc/default/grub grub2-install --no-floppy --force /dev/sda1 grub2-mkconfig -o /boot/grub2/grub.cfg

Optional, add other boot chainloaders to /etc/grub.d/40_custom menuentry "Fedora (chainload)" { insmod ext2 insmod chain set root=(hd0,msdos1) chainloader +1 }
