Replace the example path `/home/user/example.iso` with the filename of the desired ISO file, the value of `BOOT` will be ignored in this case.
* ### How do I boot without SCSI support?
* ### How do I boot without SCSI drivers?
By default, the machine makes use of `virtio-scsi` disks for performance reasons, and even though most Linux kernels include drivers for them, there are other operating systems that do not.
By default, the machine makes use of `virtio-scsi` disks for performance reasons, and even though most Linux kernels include the necessary driver for this device, for some other operating systems that may not always be the case.
If your ISO fails to boot because of this, you can add this to your compose file:
If your ISO fails to boot because of this, you can modify your compose file to use `virtio-blk` instead:
```yaml
environment:
DISK_TYPE: "blk"
```
This will use `virtio-blk` devices instead. If it still fails to boot, you can set the value to `ide` or `usb` at the cost of performance.
* ### How do I boot a x86 image?
You can use [qemu-docker](https://github.com/qemus/qemu-docker/) to run x86 and x64 images on ARM.
