Winpe test for Systemready band

[smangali-qc]

Hi @chetan-rathore,

This is regarding the WINPE test on the SystemReady band.

The device resets after UEFI when using the WINPE images from the link below:

https://developer.arm.com/documentation/102677/0500/Windows-OS-testing/Download-and-run-Windows-ADK-and-WinPE
We found a similar document on the Microsoft site for the WinPE test (Validation OS), which follows the same procedure except for replacing the .wim file with:
del d:\sources\boot.wim
ren d:\sources\ValidationOS.wim boot.wim

With this change, we were able to boot into the WinPE stage.

https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/validation-os-boot?view=windows-11

Could you confirm if this approach is acceptable, or should we strictly follow the link provided in the SystemReady band guide?

Regards,
Shiva Kumar

Hi @smangali-qc,

It looks like the problem is that your self-built WinPE doesn't work, but the ISO image (Microsoft Validation OS) downloaded from Microsoft website works fine.

In this case, since Microsoft Validation OS is not listed in the SRS, I would recommend using the Win11 ISO image downloaded from Microsoft website instead - https://www.microsoft.com/en-us/software-download/windows11arm64.

Note that in the SRS 3.1, Windows OS testing is just a recommendation rather than a requirement for self-declaring SystemReady band compliance.
