A.2.4. Booting from hard disk
It's possible to boot the installer using no removable media, but just an existing hard disk, which can have a different OS on it. Download hd-media/initrd.gz, hd-media/vmlinuz, and a Debian CD image to the top-level directory of the hard disk. Make sure that the CD image has a filename ending in .iso. Now it's just a matter of booting linux with the initrd. Section 5.1.3, “Booting from Linux Using LILO or GRUB” explains one way to do it.
我的理解下载的文件是要放在根目录下,而不是放在你的home目录里。
