ubuntu 11.10双屏显示设置问题

我刚组装的电脑自带的系统就是英文版的ubuntu，装成win7旗舰版的，可是放碟进去，就弹出错误提示，不管放什么光碟进去都是弹出错误提示。如下

'Archive: /media/UDF Volume/setup.exe[/media/UDF Volume/setup.exe]  End-of-central-directory signature not found. Either this file is not  a zipfile, or it constitutes one disk of a multi-part archive. In the  latter case the central directory and zipfile comment will be found on  the last disk(s) of this archive.note: /media/UDF Volume/setup.exe may be a plain executable, not an archivezipinfo: cannot find zipfile directory in one of /media/UDF Volume/setup.exe or          /media/UDF Volume/setup.exe.zip, and cannot find /media/UDF Volume/setup.exe.ZIP, period.


是在不懂怎么装系统，头一次接触这个系统，请路过的各位大大们帮帮啊 谢谢了
