steps for UEFI BIOS

1 – Add an entry on end on /etc/grub.d/40_custom file

cat >> /etc/grub.d/40_custom <<'EOF'
menuentry "Peppermint Custom ISO MKUSB+PinguyBuilder" {
  set isofile="/path/to/iso/peppermint_linux_customized_with_pinguy_builder.iso"
  loopback loop (hd0,gpt2)$isofile
  linuxefi (loop)/casper/vmlinuz from=${isofile} boot=casper iso-scan/filename=${isofile} quiet splash hostname=pc
  initrdefi (loop)/casper/initrd.gz
}

menuentry "Bodhi Linux Custom ISO MKUSB+PinguyBuilder" {

2 – Update GRUB2 for UEFI BIOS

grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

steps for non-UEFI BIOS

1 – Add an entry on end on /etc/grub.d/40_custom file

cat >> /etc/grub.d/40_custom <<'EOF'
menuentry "Debian 9.2 Install ISO" {
  set isofile="/path/to/iso/debian-9.2.1-amd64-netinst.iso"
  loopback loop (hd0,3)$isofile
  linux (loop)/install.amd/vmlinuz from=${isofile} iso-scan/filename=${isofile} quiet splash hostname=pc
  initrd (loop)/install.amd/initrd.gz
}

menuentry "Porteus ISO" {
  set isofile="/path/to/iso/Porteus-XFCE-v3.1-x86_64.iso"
  loopback loop (hd0,3)$isofile
  linux (loop)/boot/syslinux/vmlinuz from=${isofile} quiet splash hostname=pc
  initrd (loop)/boot/syslinux/initrd.xz
}
EOF

2 – Update GRUB2 for non-UEFI BIOS

update-grub2
