Multi-Boot flashdrive with custom Grub or custom loader (make a program)

Question

Ok guys i need help with this isuue (sorry for my english).

Well i have two operating systems, very small ones.

1. Kolibri (if you dont know it, i strongly recomend you to read about it)
2. Kubuntu

And also i have a program made in qbaisc who runs on msdos (a console program).

Ok, the two OS are .iso booteable, and the program a simple .exe. I need this two OS on my flashdrive (pendrive) and the program two. When i bootup my pc with the pendrive on it i need to have the option to select wich OS to run, and the option to run the program too. Some thing like a grub or a custom made program.

So, what do you think? how can i do this? Thanks!

Answer 1

You cannot run your program without loading the OS first. GRUB is a bootloader that will give control to the specified operating system (which in place initializes your devices/networking/etc). So unless your exe is an operating system on its own you won't be able to run it, unfortunately

One possible solution: have an installation of windows (maybe even very old version of such), cut its size down with tools you can find on the web, put your program into the installation and autorun it once that windows is booted by GRUB or whatever.
