I do have these grub entries tfoerste@t44 ~ $ cat /etc/grub.d/40_custom #!/bin/sh exec tail -n +3 $0 # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. menuentry "Gentoo Minimal" { set isofile='/home/Downloads/minimal.iso' loopback loop $isofile set root=(loop) linux /isolinux/gentoo root=/dev/ram0 init=/linuxrc looptype=squashfs loop=/image.squashfs cdroot isoboot=$isofile vga=791 dokeymap initrd /isolinux/gentoo.igz } menuentry "Gentoo Admin" { set isofile='/home/Downloads/admincd.iso' loopback loop $isofile set root=(loop) linux /isolinux/gentoo root=/dev/ram0 init=/linuxrc looptype=squashfs loop=/image.squashfs cdroot isoboot=$isofile vga=791 dokeymap initrd /isolinux/gentoo.igz } which worked flawlessly with admincd-amd64-20180320T214502Z.iso and install-amd64-minimal-20170907.iso. However with admincd-amd64-20190814T214502Z.iso and install-amd64-minimal-20190814T214502Z.iso I do get: error: file '/isolinux/gentoo' not found. error: you need to laod the kernel first. Press any key to continue ... How can I boot latest ISO images too at my notebook?
You probably need to replace "/isolinux/gentoo" with "/boot/gentoo", and "/isolinux/gentoo.igz" with "/boot/gentoo.igz". But I have not personally tested that...
