So, Hello. I'm first time on this forum. I've started to write my simple "multiboot"-compatible bootloader for computers.
The problem is that os.run and shell.run don't work for me. Os.run returns true, but doesn't actually execute my file.
How my loader works (tried to make it look something like GNU GRUB):

Lists file in computer root and finds multiboot (.mbt) scripts
Executes every line of script in built-in interpreter
Commands are "multiboot <kernel>" (to boot file), "chainload" (now can only load CraftOS), "poweroff" (you know what it does)

So, I've created test script "script.mbt", and it contains only one line: "multiboot kernel.bin"
Kernel.bin just contains while loop that just sleeps (must hang execution for a time). But nothing happens and it just returns to shell.

<At function multiboot_(target)>:

I am not sure where you define target, but it should be a valid path, which means, a string.

Target is an argument for that function.
It's first parameter of command "multiboot <target>"

I tried it and it seems to work.

script.mbt


multiboot kernel.bin

kernel.bin


print("hi")
while true do
  sleep(100)
end

not sure what you mean by it, but judging by the title you can do


shell.run("program arg1 arg2")

instead of os.run

Wait_ tried both ways. Nothing does work.
Seems strange that this thing works for someone else..

Are you using an OS or any script that may modify something on the computer? Try placing a completely new computer and putting the code on it.

Okay, seems it fixed.
Just rebooted my PC and everything worked.
Thanks. :)/>
