How can I install an iso from a portable hard drive?
The guides that I have seen require using grub2 on the local drive to load the iso on the portable drive.
I would like to boot from the portable drive. I prefer methods that are automated or elegant.
I could perform the actions form Windows 10 or Cinnamon.
Edit: The portable drive must boot in UEFI and BIOS. And I'd like to leave one ntfs partition on the hard drive for shuttling data. Currently, I'm trying to work off of https://wiki.archlinux.org/index.php/Multiboot_USB_drive. But I'm having some trouble figuring out how to incorporate uuin into the grub.cfg.
