Start-Tool.cmd opens the main setup wizard. It automatically loads the domain profile of the current computer — no configuration changes happen here, just a guided run against the standard the admins maintain. If no domain profile matches, it falls back to DEFAULT.ini.
Whether run from the GUI wizard or the CLI, every install goes through the same phases — only the interaction model differs.
Install-DbaInstance with the resolved version, edition, features, and service account.Every run can optionally emit a self-contained, animated HTML replay via -ProgressReport — offline, no CDN, playable by double-click or from a share. This is a real (test) run.
Five drive roles are resolved from the domain profile before the run starts: install (SQL Server binaries), data (.mdf/.ndf), log (.ldf), TempDB, and backup (also holds the system-database directory). A single-drive server is a per-run choice, not a config value — see the Config reference for the full standard and the single-drive override.

Expect: the instance is reachable, defaults are set, and a PostInstall report has been generated. Verify SQL Server 2025 runs separately, since media and dbatools support for it are newer.
