Here, in this quote, are some of the updated informations to this tutorial.
Recently, in the early of July 2010, Windows 7 Installation boot entry has been added into MultiBootISO.exe. We don't have to do it manually as described below.
All you need to do is:
Step 1: Download MultiBootISO, run and install it into your USB Pendrive/External Hard Disk
Step 2: As for fresh install, you only need to copy the following 3 file/directorys into the root directory of your USB(thanks for climbing for this info):
Thats it. Reboot your computer from USB. From the boot menu, choose Operating System Installers > Install Windows Vista/7
This Installation process of Windows 7/Vista will start. Good Luck.

Step 1: Run MultibootISO, install MultibootISO into your USB Storage Device(ie.pendrive, External Hard Disk). This will install Grub4dos in pendrive.
Step 2: Copy everything in Windows 7 Installation DVD into your USB storage.
Step 3: Look for the file menu.lst in your pendrive/External Hard Disk, edit it with Notepad++.
Step 4: You'll be able to see the first 9 rows as below in menu.lst
Code:

splashimage=(hd0,0)/splash.xpm.gz

Add in the below command lines after the above code:
Code:
title Install Windows 7
root (hd0,0)
chainloader (hd0,0)/bootmgr
Done. The pendrive is ready to boot and install Windows 7.
If you are confused and don't know how to edit menu.lst, then, open it with Notepad++, delete all the command lines and replace by the following command lines. Save the file and exit.

The steps mentioned in this tutorial work with Windows Vista too.
Install from Pendrive
Restart the computer. Configure BIOS to boot from Pendrive/External Hard Disk.
A boot menu will appear. You will be able to see the boot option Install Windows 7.
Use arrow key on keyboard to select Install Windows 7 and press enter.
This will enter Windows Boot Manager, choose Windows Setup [EMS Enable] and the installation will start.
Note
If you install MultiBootISO(Grub4Dos) in 2nd or 3rd partition of your external hard disk, you need to change all the (hd0,0) in menu.lst to (hd0,1) or (hd0,2).
(hd0,0) means 1st hard disk, 1st partition
(hd0,1) means 1st hard disk, 2nd partition
(hd0,2) means 1st hard disk, 3rd partition
Grub4Dos will treat your Pendrive/USB Hard Disk as 1st hard disk, but you have to define the path to 2nd or 3rd partition.
For example:
Install MultiBootISO(Grub4Dos) in 2nd partition=
Code:
title Install Windows 7
root (hd0,1)
chainloader (hd0,1)/bootmgr
Install MultiBootISO(Grub4Dos) in 3rd partition
Code:
title Install Windows 7
root (hd0,2)
chainloader (hd0,2)/bootmgr
About Menu.lst
Menu.lst is a boot menu of Grub4Dos. After install MultibootISO into pendrive/External Hard Disk, it support for booting many OS or programs. There are many entries ready made by default after installing MultibootISO. You may delete any of the entries if you don't need them.
Advantages of Using Pendrive to Install Windows 7
DVD will take 30 minutes to install Windows 7
but, Pendrive will take 15 minutes to install Windows 7. (for USB 2.0 & above)
Advantages of using Grub4Dos
There are many several ways to install Windows 7 from USB Pendrive.
Microsoft has officially released a software which can transfer Windows 7 DVD into pendrive. WintoFlash is another software will do the same thing.
However, these 2 software will only allow 1 OS at a time.
But, by using Grub4Dos, many other bootable OS or Softwares (ie, Linux, Ubuntu, Ultimate Boot CD, Partition Wizard...) are supported in one single pendrive/External Hard Disk. To view the list of supported software, you may refer the official site of MultiBootISO. If the bootable software you owned is not listed, doesn't mean it is not supported.
Besides installing Windows 7, you can make your USB become a Super System Maintenace & Emergency Rescue Tools. (i.e, recover/copy files when Windows cannot startup/lost partition/formated partition, reset or recover system/windows password, testing tools)
Below are some of the highly recommended bootable software for System Maintenance & Emergency Rescue Tools:
