首先，需要安裝grub2win,http://sourceforge.net/projects/grub2win/
其次，將iso文件放在grub2可識別的分區, 如c:\abc\iso.iso
最后，在grub2中，輸入以下指令。iso文件位置可根據實際情況替換。
loopback loop (hd0,1)/abc/iso.iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=(hd0,1)/abc/iso.iso noprompt noeject
initrd (loop)/casper/initrd.lz
boot
以上方法對於livecd嘗試有效.
But if you try to install an OS from livecd, it may failed when you try to modify the partition tables. In that case, maybe you can launch the ISO by an USB disk.
