Can't boot Windows/Ubuntu installer on new ThinkPad 13

[MultimediaMan]

Couple of things:

Windows 10: If you are attempting to use your stock Win10 install disk *.wim, you are going to be disappointed: you need to have Windows 10 ADK wim image for automated deployments. Your syntax is fine, from what I can see.

Ubuntu: There are a couple of issues here. First, I do prefer to use "chain" (but "boot" should work). This usually changes up the load order into memory (which can matter a great deal in UEFI systems). You have some inconsistencies in your ubuntu install... they could easily be how you are set up but the look "wrong" (usually linux and initrd are in the same directory)

This is what you had:

Code:

:windows_10_pro_volume
kernel ${boot-url}/windows_10_pro_volume/wimboot
initrd ${boot-url}/windows_10_pro_volume/boot/bcd         BCD
initrd ${boot-url}/windows_10_pro_volume/boot/boot.sdi    boot.sdi
initrd ${boot-url}/windows_10_pro_volume/sources/boot.wim boot.wim
boot

:ubuntu_1604_netboot_developpeurs
kernel ${boot-url}/ubuntu/16.04_netboot/linux initrd=initrd.gz auto=true priority=high vga=788 locale=fr_CA.UTF-8 kdb-chooser/method=cf url=http://xxxx:****@nas.xxxx.ca:8080/ipxe$
<assuming this is a correct path, if you are using an authenticating proxy server this command might need to be reviewed; iPXE doesn't have a proxy feature.> initrd http://xxxx:****@nas.xxxx.ca:8080/ipxe/images/ubuntu/16.04_netboot/initrd.gz
boot || goto failed
goto start

This is what I recommend:

Code:

:windows_10_pro_volume
initrd ${boot-url}/windows_10_pro_volume/sources/boot.wim boot.wim
initrd ${boot-url}/windows_10_pro_volume/boot/boot.sdi    boot.sdi
initrd ${boot-url}/windows_10_pro_volume/boot/bcd         BCD
chain ${boot-url}/windows_10_pro_volume/wimboot || goto failed

:ubuntu_1604_netboot_developpeurs
initrd ${boot-url}/ubuntu/16.04_netboot/initrd.gz
chain ${boot-url}/ubuntu/16.04_netboot/linux initrd=initrd.gz auto=true priority=high vga=788 locale=fr_CA.UTF-8 kdb-chooser/method=cf url=http://xxxx:****@nas.xxxx.ca:8080/ipxe$ || goto failed

I'm not sure is the "$" at the end of your URL= line is going to work to hide anything with with an HTTP call.
