Hi,
I am using Ubuntu as a virtual machine in VMWare.
I have used this code to write a boot loader which would write Hello world on the screen.

[BITS 16]
[ORG 0x7C00]

MOV SI, HelloString
CALL PrintString
JMP $

PrintCharacter:

MOV AH, 0x0E
MOV BH, 0x00
MOV BL, 0x07

INT 0x10
RET

PrintString:

next_character:
MOV AL, [SI]
INC SI
OR AL, AL
JZ exit_function
CALL PrintCharacter
JMP next_character
exit_function:
RET

HelloString db 'Hello World', 0

TIMES 510 - ($ - $$) db 0
DW 0xAA55

I wrote this code in the text editor in Ubuntu and saved the file as Boot.asm
Then i complied the Boot.asm to boot.bin file by using this command

nasm -f bin -o boot.bin Boot.asm

and it didn't gave me any errors. After that i copied the boot.bin file to my usb and took it to my Windows OS. After this i burned the boot.bin file to boot.img and boot.iso files.
Then i created a new virtual machhine and named it booter, when it asked for the .iso file of the OS i want to run i gave it the boot.iso file, about which i told above, then i powered on that virtual machine but it gave me this error

PXE-M0F: No boot filename received
PXE-M0F: Exiting Intel PXE ROM
Operating System not found

Please tell me what is the main problem and how can i over come that problem

The assembler does not produce executable code, let alone bootable. The .bin file will need to be linked into an executable and then possibly post-processed into a bootable image. You also need to understand that you cannot make system calls (such as int 0x10) in a bootloader as there is no operating system to service them.

You need to get hold of some documentation about creating a boot loader and bootable images. There is a series of articles here on CodeProject which explains some of the techniques to do this.
