No way! Iso generator?

BuildIso – A Lightweight ISO Builder for OSDev

BuildIsoDemo

BuildIso is a tiny, portable, dependency‑free ISO generator designed for OS developers.
It integrates directly into Visual Studio as an External Tool and produces a bootable ISO with a single click.

No VSIX.
No workloads.
No installers.
Just one .exe dropped into your project folder.

🚀 Features

Portable – one single executable, no dependencies
Bootable ISO generation (El Torito, No‑Emulation)
Automatic project name detection
Works with any OSDev project structure
Integrates into Visual Studio External Tools
Zero configuration required

📁 Project Structure

Your OS project should look like this:

MyOS/

├── BuildIso.exe

├── boot/

│ └── boot.bin

├── iso_root/

│ └── KERNEL.BIN

└── MyOS.csproj

boot/boot.bin → your 512‑byte (0x55AA) bootloader or your 2048-byte (El Torito no‑emulation) bootloader
iso_root/ → all files to include in the ISO (kernel, config, etc.)

🛠️ Visual Studio Integration

Open Tools → External Tools…
Click Add
Fill in the fields:

Title: Build ISO
Command: $(ProjectDir)\BuildIso.exe
Arguments: $(ProjectDir)
Initial Directory: $(ProjectDir)

Click OK.

You now have a Build ISO entry in the Tools menu.

(Optional) Add it to the toolbar for one‑click builds.

📦 How It Works

BuildIso:

Reads the project directory passed by Visual Studio
Detects the .csproj file
Extracts the project name
Recursively adds all files from iso_root/
Loads boot/boot.bin as the El Torito boot image
Generates a bootable ISO named:

.iso

in the project root.

🧩 Requirements

.NET 6/7/8/9/10 runtime
A valid 512‑byte or 2048-byte bootloader (boot.bin)
A populated iso_root/ directory
