WinPE reboot when using script - geri005 - 2019-01-22 08:05

Hey guys!

Using iPXE I'm able to boot to WinPE, mount my network drive and install Windows just fine.

However, I wanted to automount my network share, and start setup.exe automatically.

This is how my boot.ipxe looks like:

Code:

#!ipxe

  kernel wimboot

  initrd install.bat install.bat

  initrd winpeshl.ini winpeshl.ini

  initrd bootmgr bootmgr

  initrd boot/BCD         BCD

  initrd boot/boot.sdi    boot.sdi

  initrd sources/boot.wim boot.wim

  boot

And this is the install.bat:

Code:

wpeinit

 net use \\192.168.1.99\SZERVER /user:myuser mypwd

 \\192.168.1.99\SZERVER\iso\setup.exe

And finally the winpeshl.ini:

Code:

[LaunchApps]

  "install.bat"

Using this, WinPE boots up, then right after wpeinit, it reboots the computer.

What am I doing wrong here? Any help is much appreciated.

1. don't add bootmgr via initrd - let wimboot extract it from the .wim file
2. Have you modified boot.wim in any way, especially, have you added any drivers to it? - if yes my first suspect would be broken drivers, retry with a clean boot.wim
3. In valid format, have you tried without adding winpeshl.ini and see what happens?

1. If I don't add bootmgr, I get a bad CPIO magic error.
2. Nope, fresh download, no modifications.
3. Without winpeshl it doesn't reboot, but of course my commands are not being executed.

So if you run your commands manually, does it work? what if you run the cmd file?
does your .cmd file have proper lineendings?

You should probably investigate your CPIO issue, but hopefully not related to this.

If I run it manually, it works perfectly fine.

I tried a Windows 10 installer boot.wim before, that booted up without bootmgr, but PE refuses...

Check your batch file, most likely the network stack hasn't loaded. Try this instead. Once scripts finish executing from winpeshl.ini, Windows PE automatically reboots. Overwrite startnet.cmd instead if you want to leave the command prompt open.

I had the same problem, my solution:

Add powershell cab to boot.wim:

https://docs.microsoft.com/nl-nl/windows-hardware/manufacture/desktop/winpe-adding-powershell-support-to-windows-pe

winpeshl.ini

Code:

[LaunchApps]

wpeinit

powershell, -NoLogo -NoExit -ExecutionPolicy Bypass -File .\startup.ps1

and

startup.ps1

Code:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$ProgressPreference = 'SilentlyContinue'

Start-Sleep -s 15

CMD /C VER

net use s: \\192.168.2.13\boot password /user:boot

Write-Output (Get-Date)

Start-Sleep -s 15

Start-Process -FilePath "S:\iso\windows10\setup.exe" -Wait

boot.wim = new created with powershell!
boot.ipxe

Code:

:winpe_win10

  cpuid --ext 29 && set arch amd64 || set arch x86

  kernel http://${ipxe_server_ip}/ipxe/wimboot

  initrd http://${ipxe_server_ip}/boot/win10/winpeshl.ini                                        winpeshl.ini

  initrd http://${ipxe_server_ip}/boot/win10/startup.ps1                                         startup.ps1
