Cannot Install Windows 10 in New VM

olivierlambert

Also what Xeon model exactly?

mickwilli

@acebmxer it is UEFI, and I’ve tried with and without secure boot enabled.

mickwilli

@olivierlambert it is a “ Intel(R) Xeon(R) CPU E5-2660 v2 @ 2.20GHz”

Could you provide a crash dump?

mickwilli

@dinhngtu given it’s trying to boot from the installer, where would it save the crash dump to?

dinhngtu

@mickwilli Forget that, I just realized E5-2660 v2 is way too old for Windows 10. See the supported processors.

@dinhngtu Win10 on XCP 8.3 with E5-2600v2 works just fine for me...

dinhngtu

@Andrew Still, having an unsupported CPU makes it somewhat difficult to troubleshoot the issue, especially when it's a recent ISO. SYSTEM_THREAD_EXCEPTION_NOT_HANDLED is sometimes associated with execution of unsupported instructions (though I don't know if that's the case here). For instance, there's a poke-of-death on some newer Intel CPUs related to the Architectural LBR feature (https://docs.xcp-ng.org/troubleshooting/windows-pv-tools/#windows-bug-check-0x3b-system_service_exception-on-systems-with-newer-intel-cpus).

@mickwilli Do you know how to create custom Windows PE ISOs? It might be possible to put the boot kernel in the ISO into debugging mode, then using the Connecting to guests using serial console guide to collect a crash analysis.

mickwilli

@dinhngtu sorry, I don't know how to do that offhand. If you point me in the direction of some instructions, I'm happy to give it a go.

dinhngtu

@mickwilli You can extract the ISO, run the following command:

bcdedit /store <extracted ISO path>\Boot\BCD /set debug on
bcdedit /store <extracted ISO path>\Boot\BCD /dbgsettings serial debugport:1 baudrate:115200

Then repack the ISO.

You can also create a new ISO using this guide: https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/winpe-create-usb-bootable-drive then run the two commands above on media\Boot\BCD before you run MakeWinPEMedia.

@dinhngtu Thanks. I'll try and give that a go in the next few days and will report back.

Note that I have Windows 10 1803 installed without any issues. Trying to update to 22H2 fails with the same blue screen error as you'd expect. Sadly, no crash dump as it seems to fail very early in the boot process.

Do you get any additional BSOD details in xl dmesg ?
