Hello, in plain old bios mode (pxelinux.0) I have a working setup linke this: LABEL local MENU LABEL OS installed on ^local disk MENU IMMEDIATE COM32 chain.c32 APPEND hd0 LABEL stretch MENU LABEL Debian stable (9.x ^stretch) MENU IMMEDIATE LINUX dists/stretch/boot/vmlinuz APPEND rw root=/dev/ram0 initrd=/initrd-stretch.cramfs suite=stretch IPAPPEND 2 Now switching to syslinux.efi booting linux works fine, but I can no longer boot the Windows 10 installation installed on the first hard disk. Is this at all possible or do I need to reinstall Windows in BIOS mode?

Long answer: At the moment (and for some time/months by now), all relevant official upstream git heads (branches) FTBFS for UEFI binaries. If at some point someone manages to fix the current failures, then, perhaps someone (else) might look at "elf.c" and related source files in order to achieve loading other (U)EFI binaries. These source files might or might not be enough for that goal. Until then (if it ever happens), the current answer is that syslinux.efi (in either variant) cannot load Windows in UEFI mode, not directly and not by some workaround. Or at least nobody has ever made public such method / possibility. There are other UEFI boot managers / loaders that are capable of such task. Regards, Ady.

Will it be possible to boot syslinux.efi via network as an option from Windows boot manager? Sven -- "Thinking of using NT for your critical apps? Isn't there enough suffering in the world?"
