用的大概是写入mbr的grub，hd(0,0)是ntfs格式的，有个windowsxp系统，
kernel initrd.lz ubuntu-10.10-desktop-i386.iso文件都在根目录下，hd(0,1)下也有一份。
menu.lst代码是

这里的
代码： 全选
title Install Ubuntu
root (hd0,0)
kernel /vmlinuz boot=casper iso-scan/filename=/ubuntu-10.10-desktop-i386.iso quiet splash ro locale=zh_CN.UTF-8 noprompt --
initrd /initrd.lz
重启后报错
论坛内搜索了一下，同样的问题有几个，所以就直接复制修改他们的贴上来
论坛同样的问题有用win7硬盘安装1.04的，win7虚拟光驱加载iso的。(initramfs) /scripts/casper-premount/2-iso_scan: line 46 can't open /dev/sr0： No Medium found
Could not find the ISO=/ubuntu-10.10-desktop-i386.iso This could also happen if the file system is not clean because of an operating system crash, an interrupted boot process, an improper shutdown, or unplugging of a removable device without first unmounting or ejecting it. To fix this, simply reboot into windows, let it fully start, log in run 'chkdsk /r', then gracefully shut down and reboot back into windows. after this you should be able to reboot again and resume the installation.
chkdsk /r，无效
换用fat32格式的分区hd(0,1)，无效
用find --set-root /isomg/omg.omg 这样的代码让它自己找分区，无效
把长文件名改短，无效（看起来很蠢，因为我已经绝望了）

ok，我买了一块移动硬盘，安装成功。
在系统里还是找不到硬盘。
