*"for Retro computing purposes only"*
Some programs are directly bootable and have a nice GUI
e.g. Acronis OS Selector and Disk Director (screenshot)
How can they run wihtout underlying OS? Can this be acheived by using a minimal Linux distribution?
goal: the program should run such that it appears independent of the os (e.g you dont have to launch it from the os cmd or desktop)
also the OS should not have increase the size of the program a bit too much
Also I wonder if Qt GUI's can run like this...
