indeed , before i make my decision to choose the fedora as my work platform ,  i have tried so many variation of linux distribution , and now i just want to prefer the suitable one for me .

when refering to linux , ubuntu occur to our sight . as for me , i know linux when at the first year of my university , at that time , i can not difference the RED FLAG from red hat . i remember i download the red-flag and install it as the first time to enter the world of linux . as you see , i did not try the famous red-hat at first , but Chinese red flag .

at that time , i have no much deep impression but think it have such little sotfware and make no difference from Windows . and atfer that , i tried the red-hat also , and hold the idea linux is not such a strange and just make no difference .

at the second year , i particiated the popular RoboCup China Open contest , and we need to run the source code on ubuntu , and tha‘s the first normal usage of linux . the first touched version is about ubuntu 10.04 , which remain a typical version milestone . still a great many students prefer to use 10.04 for development because it‘s stable and simple enough to use .

atfer that , i fall in love with linux distribution , i have tried the red-hat , ubuntu , open suse , fedora , centos , deepin , and so on . at present , i just love with fedora cause it‘s stable , easy to use , and i love the the style of it .

now i just want to make notes of how to install fedora 20 i686 on Ubuntu 14.04

1. you need to download fedora 20 from official website .

2. you should to install it from USB or DVD , or as the simples way , just install from hard disk , without any third media . we choose to install from hard disk .

NOTICE: the installation is different from ubuntu , you should know that vmlinux0 and initrd0.img and fedora-*.iso must located in ext or fat partition . 

3. select Unity > search for "disk " > and open the disk application as follows :

here , we can see Partition 7 is Device : /dev/sda7 and mounted at /home , so we need to know our install media is located at /dev/sda7 .

4.ensure you need to mout the Fedora-*.iso on any directory such as /tmp:

sudo mount Fedora-Live-Desktop-i686-20-1.iso /tmp

and then enter /tmp directory to copy LiveOS into root directory of /home and copy isolinuz0 and initrd0.img to /home .

i@dosm:/tmp$ lsisolinux  LiveOSi@dosm:/tmp$ sudo cp -r  LiveOS /homei@dosm:/tmp$ cd isolinuxi@dosm:/tmp/isolinux$ lsboot.cat  initrd0.img  isolinux.bin  isolinux.cfg  memtest  vesamenu.c32  vmlinuz0i@dosm:/tmp/isolinux$ sudo cp initrd0.img vmlinuz0 /homei@dosm:/tmp/isolinux$ cd homebash: cd: home: No such file or directoryi@dosm:/tmp/isolinux$ cd /homei@dosm:/home$ lsi  initrd0.img  LiveOS  lost+found  vmlinuz0

we need to specify the bootload to load the install file  :

menuentry "install fedora 20"{
linux (hd0,7)/vmlinuz0 linux repo=hd:/dev/sda7:/
initrd (hd0,7)/initrd0.img
}

and another way is not specify the location of repo and just as :

menuentry "install fedora 20"{linux (hd0,7)/vmlinuz0 linux askmethodinitrd (hd0,7)/initrd0.img}

now let‘s begin to install !

the jounal ahead for Fedora
