Install Ubuntu on Win7 64 bit System

Install Ubuntu on Win7 64 bit System

1. Download ubuntu 64 bit system
The file name is ubuntu-11.04-desktop-amd64.iso

2. Download grub4dos
http://download.gna.org/grub4dos/

The file name is grub4dos-0.4.4.zip.

Unzip the file and copy the file list to the root path of C driver:
grldr
grldr.mbr
grub.exe

Find the file list in ubunt11.04 directory casper and copy them to the root path of C driver:
vmlinuz
initrd.lz

3. Create a file named menu.lst in the root path of driver C.
The content of menu.lst are:
title Install Ubuntu
root (hd0,0)
kernel (hd0,0)/vmlinuz boot=casper iso-scan/filename=/ubuntu-11.04-desktop-amd64.iso ro quiet splash locale=zh_CN.UTF-8
initrd (hd0,0)/initrd.lz

4. Create the file named boot.ini in the root directory of driver C
the content of boot.ini are:
[boot loader]
[operating systems]
c:\grldr.mbr="ubuntu"

copy the file ubuntu-11.04-desktop-amd64.iso in the root path of driver D.

5. install ubuntu
reboot the system
>sudo umount -l /isodevice


But nothing happened. So I failed in this way. Try other ways.

1. Download the boot tool
http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

The file name is Universal-USB-Installer-1.8.5.7.exe

>bcdedit /create /d "GRUB4DOS" /application bootsector
>bcdedit /set {ID} device partition=F:
An error has occurred setting the element data.
The request is not supported.

2. It seems that I can only install ubuntu in my C driver.

I give up and use wubi.exe in the iso file to install my ubuntu system in C driver.
