Hi there !

I have installed different Linux distros almost exclusively with dd  for 15 years.

Now I have had a problem booting the Slimbook OS iso instalation made with dd, which is already posted  @ <https://slimbook.com/en/forum/questions-and-answers-from-the-slimbook-user-community-1/question/grub-rejecting-usb-with-content-of-slimbookos-24-r112-iso-11289 >

This post is about understanding whether dd is not compatible with Slimbook OS installation iso. I will install with a Ventoy made usb, if necessary but I woud like to learn  what is the relevant difference is.

I will first try again with another dd made usb. Other machines are also reading the usb contents, from other OSes, they are also not able to boot from it. In the thread above there is a list of contents in the usb.
