I made drives like this :
/ 10GB /home 37GB swap 8GB
but there is an error :
you have not created a bootloader stage1 target device. you have not created a bootable partition.
what should I do?
Finally I myself solved this problem, I use the Fedora 20 live
disk application to change disk partitions and after this it works. Without creating
/boot or something like that.
Create a /boot partition, 500 MB would be more than enough, and format it as ext3.
