    Windows PE 5.x boot problem


    Hi

    With Windows ADK and its MakeWinPEMedia utility, I created an ISO image of Windows PE 5.x but when I start it, it does not boot.

    His BCD is:

    Code:
    C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools>bcdedit /store "C:\Users\Public\Documents\Windows_PE\ISO_debug\x32-x64\Boot\BCD"

    Do you have legacy support enabled ? As the BCD you have coded above is using winload.exe which is legacy boot..

    I can not understand this question because Windows PE should start with any type of computer.

    Anyway, I tried to start it either from a computer with the BIOS and from one with the UEFI and it does not work. Why?

    Thanks

    Instead of giving a vague description "it dsoen't work" , why don't you just explain what happens when you try to boot from the PE ?.

    - What media you are using ? ( CD/USB ). If it is USB, how it is prepared ?.

    - What kind of error you are getting - stuck at boot/blinking cursor/blue screen ?.

    I created the iso image with MakePEMedia utility and put it on a CD.

    Now, if I boot from CD with some computer (with BIOS or UEFI), I have only a black screen. Why?

    Thanks

    because you have to many DEFAULT identifier(s)

    After creating winpe boot media how did you add the second ramdisk, boot.wim to the BCD?

    Did you also add the boot files?..

    here is a BCD with 4 ramdisk boot options (Notice the identifier(s)

    Code:

    How is the PC you are trying to boot with winpe, booting now? BIOS or UEFI??

    There are two different BCD files one for legacy-bios boot and another for UEFI - the bcd you have modified and shown is the legacy boot BCD, and if you do not have legacy support enabled in your firmware - then your PC is not even trying to use the BCD store you have listed > \boot\bcd

    go into your winpe and post the BCD from this location > \efi\microsoft\boot\bcd
    that is the UEFI BCD Store

    Let me ask you - why are you trying to boot to WinPE? What is it you want to do when booted to such a limited OS

    WinPE pretty much just gives you a Command prompt and everything is done by command line

    I'm not understanding anything more.

    Using only Windows ADK, there is a guide that allows to create a CD of Windows PE 32/64 bit able to boot with every type of firmware (BIOS or UEFI) to a computer?

    Thanks
