...images with goofiboot (slint64-current-goofiboot-1.4.0.iso : /efi.img , 64 MB) - plain Linux kernel blob (slint64-current-efi-stub.iso : /efi.img , 63 MB) Question to Didier: Is the plain Linux kernel booted via EFI_LOAD_FILE_PROTOCOL after the Boot manager failed with the attempt to apply EFI_SIMPLE_FILE_SYSTEM_PROTOCOL ? (UEFI 2.4, 3.4 "Boot Mechanisms") Have a nice day :) Thomas

The ISO is built this way (of course /tmp/BOOTX64.EFI is the EFI stub): ?--- dd if=/dev/zero of=efi.img bs=1 count=0 seek=62M mkfs -t vfat efi.img MOUNTPOINT=$(mktemp -d) mount -o loop efi.img $MOUNTPOINT mkdir -...

This allows a boot of iPXE->wimboot->WinPE using an iPXE script such as: #!ipxe kernel wimboot initrd bootmgr bootmgr initrd EFI/Boot/bootx64.efi bootx64.efi initrd Boot/BCD BCD initrd Boot/boot.sdi boot.sdi initrd sources/boot.wim boot.wim boot Note that the same...

SCCM OSD Boot > com32 linux.c32 > append wimboot initrdfile=bootmgr.exe,BCD,boot.sdi,winpe.wim The UEFI version of wimboot does not expect to find its files wrapped up into an initrd; it uses the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL to retrieve them from the underlying media. It would be fairly simple to extend the UEFI version of wimboot to handle an initrd, but I have no immediate plans to do so. Michael

This got me closer, but it got to "Encapsulating winpe.wim..." and never went through the rest of the way. Ultimately PXELINUX apparently timed out and the machine rebooted.

Exactly what i need for experiments. Thanks a lot. (slint64-current-goofiboot.iso and slint64-current-efi-stub.iso were already in my collection.) It boots to "Slint installer for Slackware64-14.1" by:
