I had assumed all this time that it worked (I only tested the EFI CDROM boot) because if you read it here: https://www.gnu.org/software/grub/manual/html_node/Making-a-GRUB-bootable-CD_002dROM.html#Making-a-GRUB-bootable-CD_002dROM grub-mkrescue -o grub.iso iso This produces a file named grub.iso, which then can be burned into a CD (or a DVD), or written to a USB mass storage device. So, if I'm not mistaken that's not true when you boot from EFI (Well, I know that you are fixing it on this thread). adrian15 -- Support free software. Donate to Super Grub Disk.
