How can i put a compiled boot sector onto a USB stick or disk?

I'm busy creating a basic boot loader, it is for software that needs to run without an OS

I also want to write a small console app that moves the compiled bootloader to my SD card.

The problem I am running into is writing that specific boot loader to Sector0 on an SD card. The SD card is slotted into my SD Card slot on my laptop.

Can I accomplish this using a C# console app ? if not, what are my options on getting that boot loader on the SD card?

Update: The bootloader is written in C, I would like the console app that transfers the boot loader to be in C#

Answer 1

You could use low level IO API to write a file to a specific sector. Have a look at WriteFile documentation for more info.

Answer 2

A much easier idea would be to create an image file with your bootloader (and optionally, partition table and/or file systems) and use an external tool like dd or Image Writer to actually write the image to the SD card.
