Can you upload an empty ISO image?
all ISOs fail to run, linux, fatdog, pmagic, windows install isos, etc,
P.S. Seems to be a new issue with new version. If I run an animation then the background wallpaper does not show.
Here is latest BOOTX64.efi - it should display moon background but it does not.
If I exit to grub4efi commandline and then press ESC then I get background
Older versions used to work - is this due to recent bugfix for splashimage/graphicsmode bug ?
P.S. I can work around this bug by adding into startup menu.lst file
pause --wait=1 > nul
then background is displayed behind menu OK.
If I use pause --wait=0 > nul then the background does not appear - so delay is needed?
Even with pause --wait=1 if I try to load a second menu or navigate the existing menu then I get a memory error
Only get memory error if animation is loaded.
Ubuntu-18.04.6-desktop-amd64.iso can be successfully started。
For animation, give me a way to reproduce it.
It seems that it does not like Virtual Box 5 (booting from USB).
I tested on a real system and it does map and run the ISO - so maybe some memory issue when running under VBox ???
However, the animation / wallpaper issue is still present on a real system and i see the memory malloc errors after navigating the menu a few times same as under VBOX.
Please test。

Seems to be a bit better but still problems booting under VBOX 5. Ubuntu booting from ISO erratic.
pmagic_2018_10_12.iso does not boot
Strange 0x60 device after map ??

similar panic if boot on lenovo ideapad 300.
60 is the CD boot image. Start Linux and add the parameter '--old' after the ‘kernel’to give it a try.
kernel --old /pmagic/bzImage64 edd=on vga=normal iso_filename=%ISO% boot=live eject=no
Give this one a try。
kernel --handover /pmagic/bzImage64 edd=on vga=normal iso_filename=%ISO% boot=live eject=no
initrd /pmagic/initrd.img /pmagic/fu.img /pmagic/m64.img

That seems to work OK (bit slow maybe?) - thanks! 👍
Will we always need to specify --handover or do you intend to make it use this by default?
It will be very awkward if we have to specify --handover for some ISOs but not for others...
This version of grub4efi seems to NOT be able to work with a1ive's wimboot though (it crashes when wimboot starts to load wim into memory). Can this be fixed too?
There is no parameter '-- handover' and supports the new UEFI loading method 'LoadFile2' for Linux.
There is a parameter '-- handover' that supports the old UEFI loading method 'EFI Handover Protocol' in Linux. This method is being abandoned since Linux 6.2.
There is a parameter '-- handover' that only supports kernel versions 0x20b and above. The old method is not supported.
it seems that partedmagic 2018 does not need the --handover parameter for this new grub4efi, it boots OK without it so not sure why you told me to use the --handover parameter as it is not needed?
Both of these work...
kernel --handover /pmagic/bzImage64 edd=on vga=normal iso_filename=%ISO% boot=live eject=no
initrd /pmagic/initrd.img /pmagic/fu.img /pmagic/m64.img
kernel /pmagic/bzImage64 edd=on vga=normal iso_filename=%ISO% boot=live eject=no
initrd /pmagic/initrd.img /pmagic/fu.img /pmagic/m64.img
If it can be started without use, it will not be used.
Many people have reported that the new version of G4e cannot start old Linux, so this parameter has been added. You can ignore this parameter.
