【Ubuntu】install ubuntu 64 bit without download

　　　　Today , i want to install ubuntu 12.04 64 bit . I have installed 32 bit before ,it was very smoothly. I download ubuntu 12.04 64 bit in the same file with 32 bit . I thought the wubi would ask me to choose which one to install . But failed , it installed 32 bit defaultly without asking . Then i installed again , after deleting the 32 bit ubuntu . But to my surprise , this time spent more than 3 hours , instead of 20 minutes. After finishing installation , it became ubuntu 13.04 , and i can’t use my username and password enter the system . I google it , lots of people met this problem before ,and gave some solution . I tried a lot ,but failed . Then i asked mygoare for help . He tried to reinstall , but the wubi always download the system from internet , ignored the iso next to it . Lots of people met this problem too . Some people advanced to download “ubuntu-12.04.2-wubi-amd64.tar.xz” at first ,make sure you have dowloaded the equivalents wubi and put them togther in the same file, then run wubi and install. This way works well ~ if you meet the same problem ,try it .

　　　　Above all:

　　　　　　1. Download the ".tar.xz " file ,and you don't have to download "iso" file ,it useless. It's a bug in 64bit.

　　　　　　2. Download the correct verion wubi for the .tar.xz  . Remeber, don't download the file in http://www.ubuntu.com/download/ ( of course i mean 64bit resource), you have to download them in http://releases.ubuntu.com/ 

　　　　PS: compared 13.04, i prefer 12.04, it is LTS(a long-term support release) and have more support resouce in tech communitie.I have to say, i hate to being asked to update when i don't want.

 

　　　　Here are some resources may help.

　　　　　　dowload the 12.04.2 64bit wubi.exe

　　　　　　download ubuntu-12.04.2-wubi-amd64.tar.xz 

　　　　　　some resource about ubuntu 12.04

 

　　　　Finally, i have to say, if you think this aticle helps and want to publish to you websites, please point out the origin address here. Because i have found some tech websites publish my aticles without my blog address, which makes me unhappy. These words are typed by my hands, and i want respect, thanks
