I have laptop DELL latitude 5491 with preinstalled Windows 10 with secure boot enabled and EFI mode. After I purchased, I installed Ubuntu 20.04 next to Windows as a dualboot with still secure boot enabled/EFI. Partitions 2,3 and 5 are for Windows system, Partition 1 and 4 are for Ubuntu. On Partition 6 is stored ISO of Clonezilla live CD for backuping. So far everything is working well. In the next step I stored unpacked ISO of Parted Magic live CD on Partition 7, edited the grub menu, but booting the Parted Magic from grub menu ends in error with invalid signature for BzImage... However, when I boot the Parted Magic directly from EFI (temporary boot menu or EFI setup), system normally started. Where there may be a problem? Its look like
Partitions layout:

However path for "bootloader" of Partition 7 in EFI setup is:
\EFI\boot\bootx64.efi
When I used this path for editing 40_custom file instead of use grub.cfg file, it ends with error.
Thank you for your answers. P.
EDIT:
Option 1: I used follow edit of custom_40 file
menuentry "partedmagic" {
insmod chain
set root=(hd0,gpt7)
configfile /boot/EFI/bootx64.efi
}
When I tried to edit this file follow as:
menuentry "partedmagic" {
insmod chain
set root=(hd0,gpt7)
chainloader /boot/EFI/bootx64.efi
}
I received a error message:
Bootloader has not verified loaded image... System is compromised. halting.
Option 2: Process of resign Parted Magic's bzImage was completed success, but when i try boot this, its still with error.
...has invalid signature, you need to load kernel first.
