Hi, List Image the following case
What I Have. a USB stick with 1. a portable GRUB (either UEFI or legacy) 2. a install ISO, such as debian-9.9.0-amd64-DVD-1.iso (mayb would e a LiveCD make life easier?) What we want.Have Debian installed (could assume that we could do whatever we could, such as re-partitation the whole harddisk) The Answer to this question is most probably yes, but how. The work around is to boot with vmliunz and initrd.gz from http://ftp.debian.org/debian/dists/stretch/main/installer-amd64/current/images/hd-media/ the cost is very small as these two file size total is less than 20M I wonder if there is a way to finish install only in GRUB, without initrd involved -- Liu An
