# Windows deployment

## Target disk is unavailable

* Confirm the storage controller is supported in Windows PE.
* Add the required storage driver to deployment media.
* Disconnect removable disks that can confuse target selection.
* Confirm that the disk meets eligibility requirements.

## Windows selection is empty

* Confirm Internet and catalog access.
* Confirm the media authoring configuration permits the required release and architecture.
* Review [Catalogs](/reference/catalog.md).

## Driver pack is unavailable

* Confirm manufacturer and model identification.
* Confirm the selected Windows release and architecture.
* Check whether the catalog marks the package as legacy or targets a different model family.

Record the current deployment step, source type, and complete error. Confirm DNS, proxy, firewall, available storage, and system time before retrying.

## Deployment stops with an error

1. Record the failed step exactly as displayed.
2. Capture the complete error details without exposing secrets.
3. Collect logs before rebooting or starting another deployment.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.foundryosd.com/troubleshooting/deployment.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
