02 - How to create a USB drive that will install one of many choices of Windows OS's (Vista/Win7/Server 2008/XP)

unique hitsgodaddy tracker
Note: The instructions have been tested and seem to work OK using a Vista, Win 7, Server 2K8, Server 2008 R2 install DVDs and Win 7 PE 32bit. Let me know if you have tried it with any others. See other article for how to add XP Setup CDs.

ATTENTION: This tutorial is now superseded/replaced by Tutorial #43 if you want to keep all the DVDs as ISO files instead OR better yet (and much easier), you can make an Easy2Boot MultiBoot USB drive and just copy all your Windows Install ISO files (and 100's of others) to it.

Note: If you want to install any one of 11 different versions of Windows 7, you can simply combine all the Win 7 WIM images into one big Install.Wim file see here for details (use RMPrepUSB to prepare an NTFS USB drive for Win7 booting and copy over the entire E:\AIO\DVD folder).

This tutorial allows you to choose from Vista/Win7/Server 2K8 all from the same bootable USB drive.

You wish to create a single USB boot key/drive that will install any version of Vista, Windows 7 or Server 2008 to a system's hard disk - i.e. just as if you had all the Micro$oft Windows install DVDs in your pocket. This tutorial has been written so that you can adapt it to install as few or as many as you wish (or have room for on your USB drive!).

Note: You can also install Windows XP as well as the other OS's. To install from a Setup CD (just like booting from an XP install CD) see Tutorial #30 here.
To install XP from an image file, you first need to boot to WinPE v3 (see menu option below) and also have a copy of the XP CD files on your USB drive (or a ZIP file containing all the files) - see here for details.

This tutorial will allow you to boot from a USB flash drive (or USB hard disk) and choose from a menu:

Fig. 1 This menu was made using menu2.lst (renamed to menu.lst).

Equipment required
  • Source Microsoft DVDs or ISOs for Vista/Win7/Server 2008 (note OEM DVDs will usually not work) (Win7 ISOs here - use Digital River links, some other links may be broken)
  • A USB drive large enough to fit all source files onto (min 4GB for one DVD, 32GB+ for all DVDs)
  • RMPrepUSB v2.1.617 or later
  • Windows 7 WAIK (click to download)
  • A Windows Vista/Windows 7 computer to prepare the USB drive files (Win7/Vista required as BCDEdit.exe is required)
  • The MultiWin9.Zip file (click the link to download from the Tutorials download section)

  1. Download and install the Windows 7 WAIK to obtain ImageX utility and WinPE OS (you MUST use Windows 7 RTM WAIK version or the menu.lst patches to bootmgr will not work)
  2. Make a new folder called C:\MYUSB
  3. Copy bootmgr (or make multiple copies of bootmgr)
  4. Copy the BCD files from each DVD and modify them
  5. Copy the boot.wim file from each DVD (a .WIM file is like a .ZIP file)
  6. Modify each boot.wim file
  7. Copy over the Windows source file(s) from each DVD (usually sources\install.wim)
  8. Partition, format and create the USB drive using RMPrepUSB
  9. Boot from the target system using your new USB install drive

Final structure of C:\MYUSB folder (note: folder names must not contain spaces):

changeBCD.cmd (does not need to be copied to the USB drive)
zbootmgr.exe (does not need to be copied to the USB drive)
ModBootWim.cmd (does not need to be copied to the USB drive)
grldr (only on USB drive after running grub4dos install in step 8)


boot.sdi (BSOD if not present!)

\OEM folder (optional)
unattend.xml (optional)
\OEM folder (optional)
unattend.xml (optional)
Install.wim + all other files from DVD \Sources folder
\OEM folder (optional)
unattend.xml (optional)
Install.wim + all other files from DVD \Sources folder
\OEM folder (optional)
unattend.xml (optional)
Install.wim (+ all other files from DVD \Sources folder if not RC2 version)
\OEM folder (optional)
unattend.xml (optional)
Install.wim (+ all other files from DVD \Sources folder if not RC2 version)
\OEM folder (optional)
unattend.xml (optional)

How it works:

PC boots from USB -> grub4dos loads -> menu.lst presented -> bootmgrx selected -> \boot\bcx selected -> \sources\bootx.wim loaded -> winpeshl.exe -> winpeshl.ini -> mysetup.cmd runs -> windows setup directed to correct install.wim file by mysetup.cmd file.

Step-by-step instructions

1. Download and install the Windows 7 WAIK to obtain the ImageX utility
For instructions on how to do this, please refer to the first part of my tutorial here.
Follow the instruction up to the point where a WinPE folder has been created (Step 1)
You can create either an x86 version or an amd64 (64-bit) version (x86 recommended as 64-bit WinPE will not boot on 32-bit only CPUs such as Atom N270/netbook CPUs).

2. Create a new folder called C:\MYUSB on you hard drive.

Copy and extract the contents of the latest version of MultiWin9.ZIP file in the Beta Downloads - Miscellaneous Tutorials section of this website to the C:\MYUSB folder.

Latest version of zbootmgr.

Note: If you delete menu.lst and rename menu2.lst to menu.lst you can omit step 3.1 below (recommended).

3. Copy bootmgr from the c:\pe86\ISO folder made in step 1 above to your new C:\MYUSB folder.

(before you follow the next 3 instructions in section 3.1 below, read the footnote at the bottom of this page to save you some work - you are recommended to use menu2.lst and skip section 3.1 but you MUST use the Win7 RTM version of bootmgr with a CRC32 value of EE471B58!)

3.1 Now run the program zbootmgr.exe and select the \MYUSB\bootmgr file.
Click the Save button and save the modified bootmgr as bootmgr1.
Repeat this 5 more times to save 6 versions (bootmgr1, bootmgr2, bootmgr3... bootmgr6) of the file.

4. Copy the \boot\BCD file from each different source Windows install DVD to C:\MYUSB\boot\bcx as follows:
From the Windows 7 64-bit DVD, copy the file \boot\bcd to C:\MYUSB\boot\bc1
From the Windows 7 32-bit DVD, copy the file \boot\bcd to C:\MYUSB\boot\bc2
From the Windows Vista 64-bit DVD, copy the file \boot\bcd to C:\MYUSB\boot\bc3
From the Windows Vista 32-bit DVD, copy the file \boot\bcd to C:\MYUSB\boot\bc4
From the Windows Server 2008 64-bit DVD, copy the file \boot\bcd to C:\MYUSB\boot\bc5
From the Windows Server 2008 32-bit DVD, copy the file \boot\bcd to C:\MYUSB\boot\bc6

Now run the WAIK Deployment Tools Command prompt from
Start Menu - All Programs - Microsoft Windows AIK - Deployment Tools Command Prompt
(right-click and choose Run as Administrator) - it should show a command prompt like:

C:\Program Files\Windows AIK\Tools\PETools>

Now type the characters in bold print below (press the Enter key to execute each command):

C: (type the drive letter where you have stored the MYUSB folder - in this case C:)
CD C:\MYUSB (change to the folder where you placed the source folder)
--> should now say C:\MYUSB> as prompt

this changes the current location to the same folder as your source folder and runs ChangeBCD.cmd from the C:\MYUSB folder. You will be asked for a BCD number.
Enter 1 (if you have a bc1) - it should modify the existing bc1 file so that it looks for boot1.wim instead of boot.wim.

Repeat this for all bcx files that you have added.

(Tip: leave the command prompt window open - you will use it again in Step 6).

4.1 Copy the boot.sdi file from C:\PE86\ISO\boot folder to C:\MYUSB\boot\boot.sdi - if not present you will get a BSOD error before it starts to load the boot.wim file.

5. Copy the \sources\boot.wim file from each DVD to the MYUSB\Sources folder as follows:
copy (Win7 64 dvd)\sources\boot.wim to
copy (Win7 32 dvd)\sources\boot.wim to
copy (Vista 64 dvd)\sources\boot.wim to
copy (Vista 32 dvd)\sources\boot.wim to
copy (server2008 64 dvd)\sources\boot.wim to C:\MYUSB\sources\boot5.wim
copy (server2008 32 dvd)\sources\boot.wim to

Note: It is important to keep the same numbering, even if you are only installing one or two of these OS's.

6. We now need to add two files from the multiwin.ZIP file you downloaded to each OS bootx.wim file (a wim file is like a zip file)
as follows,
so that Windows setup will find the correct install.wim file:

This now involves typing some tricky commands (but I have automated this for you - read the Tip section below):
Right-Click on Start Menu - All Programs - Microsoft Windows AIK - Deployment Tools Command Prompt (opens command prompt window)
(right-click and Run as Administrator)
type MD C:\MOUNT to create an empty MOUNT folder
type IMAGEX /mountrw C:\MYUSB\sources\boot1.wim 2 c:\mount to mount the 2nd image in the wim file onto your C:\mount folder*
type copy C:\myusb\w764\*.* C:\mount\windows\system32\*.* to copy over the winpeshl.ini and mysetup.cmd files
type IMAGEX /unmount /commit C:\MOUNT to save the changes
*if image #2 does not exist then use image #1)
You would need to change the highlighted portions for each one as appropriate - but I have automated this for you so you can use the ModBootWim.cmd script as follows:

Tip: I have included the file ModBootWim.cmd in the ZIP download which will automate this for you. Run the WAIK Deployment Tools Command prompt from
Start Menu - All Programs - Microsoft Windows AIK - Deployment Tools Command Prompt
(right-click and choose Run as Administrator)
and change to the C:\MYUSB folder (or whatever folder you have used instead - see step 4 for example commands).
Now type ModBootWim and it will run the above commands for you.
