What install instructions did you follow?

Once the Fedora 21 OS install is complete, you should see a login prompt. Log in using the credentials you set up during the OS install. Then execute the commands.

Yes, I made a mistake . I thought any Fedora full ver need to install first and there should be some os for amahi , Its wrong

I got It its must Fedora 21 server version , and need to Amahi wiki instruction yeh ,
BTW its must need to install by CD/DVD right ? USB not supported yeh , I boot with USB it cant booted , I meant its asking
"install fedora server 21" when select that it went to some command promt no more language selection
Let me try with DVD
Thx a lot
