Hello all, I'm trying to have the Gentoo Live CD ISO as a recovery media in grub.
I tried all the options I could think off in a custom grub menu entry like this: menuentry "Gentoo ISO" { set cmdline="root=/dev/ram0 init=/linuxrc dokeymap looptype=squashfs loop=/image.squashfs cdroot initrd=gentoo.igz BOOT_IMAGE=gentoo" loopback loop /path/to/iso/install-amd64-minimal-20180206T214502Z.iso linux (loop)/isolinux/gentoo $cmdline isoloop=/image.squashfs initrd=gentoo.igz vga=791 BOOT_IMAGE=gentoo initrd (loop)/isolinux/gentoo.igz } It boots the live CD kernel, it even asks for the keymap but then it fails to mount the root device. Any idea how to properly boot the iso from grub?
