[try]  not find ACPI,what is it?

Solved the issue by disabling ACPI management in BIOS.

See nvidia issue report on http://http.download.nvidia.com/XFree86/nforce/1.0-0306/KnownProblems.html

Hope this helps.

系统win7，C盘ntfs分区
准备安装ubuntu-10.04.1

将ubuntu-10.04.1-desktop-i386.iso安装文件用虚拟光驱加载，运行wubi.exe，选择第一项完整的安装，然后设置让帮助从CD引导启动
程序将自动在C盘建立ubuntu文件夹，同时准备必须的文件，其中引导的grub.cfg文件（C:\ubuntu\install\boot\grub）内容：
代码:
......此处省略
# TBD try to boot directly from kernel/initrd within the ISO via the grub2 loop module

search -s -f -n /ubuntu/install/boot/vmlinuz

menuentry "Normal mode" {
    linux /ubuntu/install/boot/vmlinuz debian-installer/custom-installation=/ubuntu/install/custom-installation noprompt quiet splash  boot=casper ro debian-installer/locale=zh_CN.UTF-8 console-setup/layoutcode=us console-setup/variantcode= --  rootflags=syncio
    initrd /ubuntu/install/boot/initrd.lz
}
......此处省略



然后重启系统，选择进入ubuntu安装，一段时间后，出错，提示
unable to find a medium containing a live file system.
更换了几台不同的电脑尝试，问题依旧（其他电脑都是windows xp系统）



然后我修改上述grub.cfg文件如下，增加iso-scan/filename=/ubuntu/install/installation.iso：
代码:
......此处省略
# TBD try to boot directly from kernel/initrd within the ISO via the grub2 loop module

search -s -f -n /ubuntu/install/boot/vmlinuz

menuentry "Normal mode" {
    linux /ubuntu/install/boot/vmlinuz debian-installer/custom-installation=/ubuntu/install/custom-installation iso-scan/filename=/ubuntu/install/installation.iso noprompt quiet splash  boot=casper ro debian-installer/locale=zh_CN.UTF-8 console-setup/layoutcode=us console-setup/variantcode= --  rootflags=syncio
    initrd /ubuntu/install/boot/initrd.lz
}
......此处省略


重启系统安装，一切正常。

3.安装完成linux后，xp没有引导进入了？

上网查了一下原因,估计是在安装的时候没有创建grub引导程序,于是在Ubuntu终端执行 下面命令:
　　sudo update-grub
