这个问题搞了我一整天，积累下不少教训，下面记录如下：
在安装ubuntu10.10 LiveCD时，提示(initramfs) Unable to find a medium containing a live file system错误。
然后就觉得是CD的问题？用另外一个电脑虚拟机实验安装，没有问题。
重新刻录LiveCD，还是有这个错误
刻录maverick-dvd-amd64还是有这个问题。
得，那就搜吧，baidu好一阵，搜得结果都不知所云。

今晚忽然想起来，应该用google搜，我操，果真是国外论坛专业，一搜就解决了问题。
原来是哥的新电脑主板太先进了，把CDROM插到SATA3接口上了，ubuntu10.10愣是认不出来！
换接到SATA2口，立即解决问题。
看人论坛上说的：
Evidently, in addition to disabling the quick-boot option in the bios, you MUST use the left USB port on the Asus 1018p.
I was trying to install using the right usb ports, which are USB 3.0, however are apparently not bootable.
看到这句，哥就觉得是硬件问题了。
后来竟然直接找到了问题答案：
I was just looking at this thread since I had a similar problem trying to install 10.10 from CD. I finally figured it out. I tried to think about everything I had changed since I had previously installed 10.04. I remembered changed the SATA port that the DVD drive plugged into, based on advice for installing OSX (which I had been trying to do). I moved the connector back and sure enough, no more "..unable to find live file system" problem.

这次的教训：
以后遇到问题再也不baidu了，必须google，google才是专业的！
