Well that has crossed my mind.... though i do not have any stick or SD.... its all in storage for now.
But you are very welcome to add your ways of doing this.
And USB seems to me one of the most popular ways to do so.
My latest take on this is very oldschool..... since Grub is not abel to run an iso directly.
I'm on the indirect trace... a floppy-size base (1,44Mb + 35 Kb .bat) for execution slax-style.
Although i have not yet searched enouth, and viewed all other options...
But it sure could do the job if the files needed aren’t to much work. (creating a .bat file for VL)
Then it would be possible to install by 3 simple commands.... by freedos.
One execute freedos from Grub, cd to dir, and run............
