   Can you dd your USB stick with http://mirror1.slitaz.org/iso/rolling/slitaz-rolling-core64.iso or
   http://mirror1.slitaz.org/iso/rolling/slitaz-core-5in1.iso (built on 2018-May-20) and boot your laptop ?

   I have tested both with qemu only:
   $ qemu-system-x86_64 -m 512 -bios /usr/share/qemu/x64/OVMF.fd -cdrom slitaz-rolling-core64.iso
   $ qemu-system-x86_64 -m 512 -bios /usr/share/qemu/x64/OVMF.fd -hda slitaz-rolling-core64.iso

   If the boot is ok, you should upgrade the syslinux-extra package to get /usr/bin/isohybrid up to date.

   /efi/boot in the iso image is not used; it reflects /boot/isolinux/efi.img vfat content where any file has the executable flag.

   Ok, I've just tried both http://mirror1.slitaz.org/iso/rolling/slitaz-rolling-core64.iso and http://mirror1.slitaz.org/iso/rolling/slitaz-core-5in1.iso

   Same result - it's not seen by the laptop boot manager as a bootable device.

   Right, makes perfect sense now what you're saying about the executable flag.

   Please, don't hesitate to ask me to try something or let me know otherwise how I can be helpful to get this to work.

   The boot time may be a bit long.

   hi @Bellard, no success on my end - I've tried both of my UEFI bootable devices. It's still the same issue - boot manager doesn't even see USB stick.

   Funny enough, it does boot on my VBox which is set to EFI bootable mode. Btw this image boots much faster on my VBox than the one you sent few days ago so I don't know why you're saying it would be slow. The previous one was real slow to boot.

   On the side note, I updated my Slitaz system and the image does build now with tazlito though with the same result - real HW EFI boot manager doesn't see it.

   I tried again making it the way I was trying it previously - I place my _big_ ~65MB files to addfiles/rootcd/efi/boot and build the image. If you remember, this wouldn't work previously but now it did work (I guess it's due to updated system utils as you mentioned). Syslinux x64 version starts fine, it shows loading the rootfs.gz and then it goes to reboot. My guess is that my bzImage is not built with x64 gcc and libs. Can this be the reason?

   I'll be trying to dig into this direction here. I just don't know how to help you understand the problem where the stick is not even seen. What is it happening to the image when I explicitly place files to addfiles/rootcd/efi resulting in the image that is properly marked and detected as UEFI bootable and doesn't happen if I don't use this folder?

   Totally wild idea - can it be so that the EFI executable kernel file must be named either bootia32.efi or bootx64.efi ?

   @st_user:
   bootx64.efi will be lunched without arguments : no rootfs*.gz.
   Did you disable the secure boot ?
   Can you boot EFI shell ? and run startup.nsh ...

   Now I place Syslinux x86 version as bootia32.efi to addfiles/rootcd/efi/boot and the stick is not seen by the boot manager either. Like I said, Syslinux x64 with bootx64.efi was detected and started just fine. So is it then x86 vs x64 issue? Does the kernel need to be compiled as x64 and placed as bootia32.efi?

    @bellard, Secure boot is disabled.

    How do I boot to EFI shell? I keep reading about it but wasn't able to get to it on my laptop. On VBox it stars by default.

    Press the hot key to launch the EFI boot menu. Maybe F7 or F2 ...

    hi @Bellard,

    I can't get to UEFI shell on my Lenovo Ideapad 320s. My finding so far is that it either needs UEFI shell from external USB or UEFI shell can be enabled with special Lenovo software.

    But I've run tests with more HW: I've tried a couple of regular Dell laptops (e6510 and latitude e5520). Result is still the same - no bootable media found when I switch booting to the UEFI mode.

    Funny enough, after switching to UEFI mode, it's possible to point to a specific file to boot from (see the image I attached). I do point to the startup.nsh but with the same result - it starts with no bootable media found error. Just in case it could trigger any thought on your end.

    Well, next thing I'll try to get to UEFI shell either on Lenovo or one of the Dells.

    p.s. Sorry, messed up attachments - should be just 2 files.

    Can you retry with http://mirror1.slitaz.org/iso/rolling/slitaz-core-5in1.iso (2018-May-30 12:07:11) ?
    GPT support is reworked see http://hg.slitaz.org/wok/rev/f582dbc28a10
    '# parted -l' and '# fdisk -l' are happier with it

    I just tried it on 3 different laptops - no luck, still not seen at boot up.

    With the new image I see now that there's only 1 partition available for mounting - with the UEFI content one. Previously there was 2 partitions. Though file shows it does have MBR.

    file slitaz-core-5in1.iso
    slitaz-core-5in1.iso: DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,1), end-CHS (0x3ff,254,63), startsector 1, 124927 sectors
