I am using ubuntu-builder_2.4.1-gb3-1_all.deb Version 2.4.1 Debian package (Gambas 3) in my host machine which runs Ubuntu 13.04. I am using the same version 64-bit iso to customize it using the ubuntu-builder.gambas. Everything works fine, and I created the iso file. But when I run it in qemu or virtualbox, it shows a popup message box saying /casper/vmlinuz.efi: file not found
. The screenshot shown below is from VirtualBox:
In the casper directory of the iso made by the builder there is no file named vmlinuz.efi
Okay, I found out a way to rectify this problem. All you have to do is to remove the installed kernel in the iso file, and install a new one.
1) Remove initrd.img and vmlinuz
2) Remove the kernel files
3) Install kernel generic version
This one solves my problem.
