The device install log is particularly helpful if rollback occurs during the sysprep operation (extend code 0x30018).
To resolve a rollback that was caused by driver conflicts, try running setup using a minimal set of drivers and startup programs by performing a [clean boot](https://support.microsoft.com/kb/929135) before initiating the upgrade process. Also check to be sure that your drivers are properly signed. For more information, see [Remove unsigned drivers](quick-fixes.md#repair-unsigned-drivers).
