<br>
I have dnsmasq (built-in tftp enabled) and apache.<br>
<br>
Legacy PXE Boot is working fine.<br>
<br>
I also want to boot Win10 Install Images through UEFI.<br>
<br>
This works when I use ipxe as a boot-file in dnsmasq, as expected.<br>
I'm able to chainload wimboot/win10 from CLI or load from an embedded script in ipxe, both works.<br>
<br>
But I would like to boot grub (BOOTX64.EFI) and chainload ipxe from it.<br>
Well, this also work, at the beginning.<br>
<br>
After UEFI-PXE boots my grub.cfg shows up.<br>
I select "Windows 10 Install" which looks like this in grub.cfg:<br>
<br>
menuentry "Windows 10 Install" --id win10 {<br>
insmod chain<br>
chainloader (tftp)/ipxe.efi<br>
}<br>
<br>
<br>
this loads the ipxe.efi from the tftp, and the embedded ipxe-script loads a boot.ipxe from apache, this also works,<br>
I see it in the logs and ipxe says "ok".<br>
<br>
But after that the Win10 install does not start, it will just fall back to the grub.cfg and no keypresses are recognized anymore.<br>
<br>
<br>
Do someone have a clue what is going on or what I can do to debug?<br>
Is there something missing?<br>
<br>
TIA,<br>
