I'm trying to make an installer for a program and for that program to work I need to alter a few important windows files
I'm trying to make it like this:
plug in the usb
boot from the usb
wait for the installer to finish
boot windows and taaada program installed
I used all kinds of variations of Ms-Dos to do this but all of them don't copy my program's files or fail at something else
Any idea how to make something similar ?
You could try NTFSDOS if you want to keep being in DOS, or you could use some Linux distribution and mount the harddrives partition that way.
