Dell SupportAssist Pre-Boot System Performance Check

The Pre-Boot System Performance Check is essential for identifying hardware issues before the operating system loads. Users should initiate this check when faced with persistent boot issues.

• Keep an eye on any error messages that appear—these provide crucial clues.
• If issues persist, consider booting in Safe Mode to troubleshoot further.
