It sounds like you're experiencing a frustrating situation with your Dell 7750 and the Windows 11 installation process. Here are some steps you can take to troubleshoot and potentially resolve the issue:
- Check USB Drive and Media Creation Tool: Ensure that the USB drive you created using the Windows Media Creation Tool is functioning properly. Sometimes, the USB drive can become corrupted. You might want to recreate the installation media on a different USB drive if possible.
- BIOS Settings: Enter the BIOS/UEFI settings by pressing the appropriate key (usually F2 or Del) during startup. Make sure that:
- The boot order is set to prioritize USB drives.
- Secure Boot is disabled, as it can sometimes interfere with installations.
- The system is set to UEFI mode instead of Legacy mode.
- Perform a Hard Reset: Disconnect all peripherals, remove the battery (if possible), and hold the power button for about 15 seconds. Reconnect everything and try booting from the USB again.
- Use Windows Recovery Environment (WinRE): If you can access WinRE, you might be able to perform a system restore or a startup repair. To access WinRE, you can force the laptop to shut down three times during boot to trigger recovery options.
- Check for Hardware Issues: Since the laptop was serviced, there might be hardware issues that are causing the blue screen. If possible, run hardware diagnostics provided by Dell to check for any underlying problems.
- Try Safe Mode: If you can get into WinRE, try booting into Safe Mode. This can sometimes allow you to troubleshoot further or uninstall problematic drivers.
- Consider a Clean Installation: If all else fails, you may need to perform a clean installation of Windows 11. This would involve formatting the drive, so ensure you have backups of any important data.
If these steps do not resolve the issue, it may be worthwhile to escalate the matter with Dell support or seek assistance from a local technician who can physically inspect the laptop.
