The operating environment of this tutorial: Dell XPS 13, Windows 11
1. Check Installation Media Integrity
Corrupted or improperly created installation media is a common cause of setup failure. Ensuring the bootable USB or DVD is correctly prepared helps eliminate this factor.
- Redownload the official Windows ISO file from Microsoft’s website using the Media Creation Tool.
- Use a reliable tool like Rufus or the official tool to create a bootable USB drive.
- Verify the SHA-256 hash of the ISO matches the one published by Microsoft.
Always use a USB drive with at least 8GB capacity and format it as FAT32 before writing the ISO.

2. Disconnect Non-Essential Peripherals
External devices can interfere with the installation process, especially those that are not plug-and-play compatible or require specific drivers.
- Remove all USB devices except the installation media.
- Disconnect printers, external hard drives, webcams, and docking stations.
- Install Windows using only the keyboard and mouse directly connected to the PC.
Use USB 2.0 ports instead of USB 3.0/3.1 if available, as they are more widely supported during early boot stages.

3. Update or Reset BIOS Settings
Outdated or misconfigured BIOS settings can block the Windows installer from properly detecting hardware or loading drivers.
- Access the BIOS/UEFI by pressing F2, F10, or Del during startup.
- Update the BIOS to the latest version provided by your manufacturer’s support site.
- Load default settings or optimized defaults to clear any incorrect configurations.
- Ensure Secure Boot is enabled and CSM (Compatibility Support Module) is disabled for UEFI installations.
Incorrect boot mode (Legacy vs UEFI) can cause installation failure—match the mode to your installation media setup.

4. Run SetupDiag to Identify Failure Cause
SetupDiag is a Microsoft diagnostic tool that analyzes failed Windows installation logs and reports the root cause.
- After a failed installation, access the system via a working OS or recovery environment.
- Download SetupDiag from the official Microsoft GitHub repository.
- Run the tool from Command Prompt: SetupDiag.exe > diag_result.txt
- Review the output file to identify the specific error code or component failure.
5. Clean the Hard Drive Using DiskPart
Existing partitions, corrupted file systems, or leftover upgrade files can prevent a clean installation.
- Boot from the Windows installation USB.
- On the setup screen, press Shift F10 to open Command Prompt.
- Type diskpart, then press Enter.
- Run list disk to identify the target drive.
- Select it with select disk X (replace X with the disk number).
- Execute clean to erase all partitions and data.
- Exit DiskPart and proceed with installation.
This action permanently deletes all data—ensure backups are completed before proceeding.
