 ### What image formats are supported?
 
-  You can set the `BOOT` URL to any `.iso`, `.img`, `.raw`, `.qcow2`, `.vhd`, `.vhdx`, `.vdi` or `.vmdk` file.
+  The `BOOT` URL accepts files in any of the following formats:
 
-  It will even automaticly extract compressed images, like `.img.gz`, `.qcow2.xz`, `.iso.zip` and many more!
+  | **Extension** | **Format**   |
+  |---|---|
+  | `.img`       | Raw           |
+  | `.raw`       | Raw           |
+  | `.iso`        | Optical       |
+  | `.qcow2` | QEMU         |
+  | `.vmdk`   | VMware      |
+  | `.vhd`       | VirtualPC   |
+  | `.vhdx`     | Hyper-V     |
+  | `.vdi`        | VirtualBox |
+
+  > [!TIP]
+> It will also accept `.img.gz`, `.qcow2.xz`, `.iso.zip` and many more, as it automaticly extracts compressed files.
