Create a Windows Vista/WinPE dual boot

  • Artikel

For the guys who want to play with BCDEDIT, this is a good exercise !

  1. Create a custom WinPE image

    Execute "Windows PE Tools Command Prompt” from Start | Programs | Windows AIK

    1. copype.cmd x86 C:\WinPE_x86

      image

      The following folders are created with the listed content :

      image

    2. Mount the default winpe.wim

      Imagex /mountrw c:\winpe_x86\winpe.wim 1 c:\winpe_x86\mount

    3. Packages injection :

      1. peimg /install=*HTA* c:\winpe_x86\mount\Windows
      2. peimg /install=*WMI* c:\winpe_x86\mount\Windows
      3. peimg /install=*MDAC* c:\winpe_x86\mount\Windows
      4. peimg /install=*SCRIPT* c:\winpe_x86\mount\Windows
      5. peimg /install=*XML* c:\winpe_x86\mount\Windows
      6. Peimg /inf=e:\win_vista_32\b57nd60x.inf c:\WinPE_x86\Mount\Windows

    4. ImageX /unmount c:\winpe_x86\mount /commit

    5. Copy c:\winpe_x86\winpe.wim c:\winpe_x86\ISO\Sources\boot.wim

    6. If you want to create an ISO of this WinPE image :

      Oscdimg –l"WinPE 2.0" -n -bc:\winpe_x86\etfsboot.com c:\winpe_x86\ISO c:\winpe_x86\winpe_x86.iso

  2. Copy C:\WinPE_x86\ISO to C:\WinPE

  3. Create the RAMDISK device in the BCD

    1. bcdedit /export C:\BCD_BKP -> hey, make a copy of the current BCD before altering it !
    2. bcdedit –store c:\boot\bcd /create {ramdiskoptions} /d "Ramdisk options"
    3. bcdedit /set {ramdiskoptions} ramdisksdidevice partition=c:
    4. bcdedit /set {ramdiskoptions} ramdisksdipath \WinPE\boot\boot.sdi

  4. Create a new loader entry in the BCD

    1. bcdedit -create /d “WinPE 2.0" /application OSLOADER
    2. A GUID has been assigned to the new loader entry, note that GUID by executing the following command line :
      bcdedit /enum all | more

  5. Create the OS Loader object

    1. bcdedit /set {NewGUID} device ramdisk=[c:]\WinPE\sources\boot.wim,{ramdiskoptions}
    2. bcdedit /set {NewGUID} osdevice ramdisk=[c:]\WinPE\sources\boot.wim,{ramdiskoptions}
    3. bcdedit /set {NewGUID} path \windows\system32\boot\winload.exe
    4. bcdedit /set {NewGUID} systemroot \windows
    5. bcdedit /set {NewGUID} detecthal yes
    6. bcdedit /set {NewGUID} winpe yes
    7. bcdedit /displayorder {current} {NewGUID}

Please be careful with the syntax as its quite strange sometime and that will be fine !

When you will restart your computer, you will see the Boot Manager menu that will let you choose between Windows Vista and WinPE.

This procedure works also for Windows Server 2008...

Note that this procedure is provided "as is" with no warranty nor supportability engagement. It does not engage Microsoft at all.
Nevertheless if you consider this not clear, incomplete or inadequate, please let me know !

    Hi,
    6 years later, your tutorial is still very helpful for people like me who are not bcdedit experts...
    It works on Windows 7 embedded !

    Thank you very much !

    Hi, I have already created dual boot of Windows 7 PE x86 & x64 (Probably PE 2.0) but i have few leagcy systems which are not able to boot from this PE. I have another disk have Windows XP PE (Probably PE 1.0) and it doesn't have any .wim file. I have include this PE boot to my latest PE. (Windows 7 PE (x86 + x64) + Windows XP PE) . Is there any way to do it. The main problem i am facing is to path entry in BCD file file. Please help.
