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

[f4242]

Hello,

I tried what you suggested, but I still have the same failure. I would like to add that the current setup work fine with various Dell and Lenovo desktops and laptops. This issue only occurs with the Lenovo Thinkpad 13 (the 2017 edition, the 2016 edition works fine too). I have two TP13 2017 and they both fail to boot the installers, so I don't think this is a defect.

My modified configuration is now:

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 http://xxxx:****@nas.xxxx.ca:8080/ipxe/images/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/preseeds/ubuntu-16.04.developpeurs.preseed || goto failed

About the Windows image, I'm using the image generated by MS Deployment Workbench.

Thanks!
