Problems installing ML on new iMac!

Hey guys i have a iMac from 2012 and a 2010. I made a bootable cd on my MBP and used it to do a clean install on the MBP and it worked perfectly! now im using the same cd to install ML och my imac but when it's installing it says that " can't download the additional components needed to install mac osx" is it just because i made a bootable cd from another computer or whats happening? i did a clean install and iv already removed everything on my imac so i can't really go back what should i do?!?!

should i install lion again and do a bootable cd from the imac or does anyone have any suggestions?!?!?

Please help!

 

solved it! my cd was really dirt but now its working!
