I need to make a usb drive bootable using a tool, I am asking this question here as i cannot use any third party tool to do this and i need to implement this in my code in C++.
The req are: user will insert an external USB hard disk on the machine.
and when he clicks "make bootable", the tool will first format the usb disk, I will be using format.exe to format the disk, I already have the boot files ready with me (ntldr, bootfix etc with me).
If i only copy these files to the usb disk, i will not be able to boot from this usb disk because:
The MBR on the disk is not present.
So with c++ how can i write the MBR on the USB hard drive so that it will point it to the boot files on the same disk so that my USB hard disk becomes bootable.
I am sure there is a way, but i am unaware what is it.
