Hello world using nasm in windows assembly

The biggest problem is that you are trying to use Linux interupts on windows!
int 80 will NOT work on windows.

We are using Assembly, so your entry point can be ANY label you want. The standard entry point that ld looks for is _start, if you want to use another label, you need to tell ld with the -e option
So if you want your start label to be main, then you need

global main
ld -e main test.o -o test.exe

If you are going to use NASM on Windows, I will recommend using GoLink as your linker.
Here is a simple windows console app:

STD_OUTPUT_HANDLE   equ -11
NULL                equ 0

global GobleyGook
extern ExitProcess, GetStdHandle, WriteConsoleA

section .data
msg                 db "Hello World!", 13, 10, 0
msg.len             equ $ - msg

section .bss
dummy               resd 1

section .text
GobleyGook:
    push    STD_OUTPUT_HANDLE
    call    GetStdHandle

    push    NULL
    push    dummy
    push    msg.len
    push    msg
    push    eax
    call    WriteConsoleA 

    push    NULL
    call    ExitProcess

makefile:

hello: hello.obj
    GoLink.exe  /console /entry GobleyGook hello.obj kernel32.dll  

hello.obj: hello.asm
    nasm -f win32 hello.asm -o hello.obj
