Using Rufus on an older Dell PC doesn’t allow the Windows 11 installation to start from the USB drive
You're facing a tricky setup situation with your Dell Precision T3600. It seems the Windows 11 installation isn't behaving as expected in UEFI mode, showing artifacts before restarting to the old OS. The issue might be related to boot configuration or hardware mismatch. Since reseating RAM resolved the problem, it suggests a possible driver or bootloader conflict. Try checking the BIOS settings for any changes made during installation and ensure the correct boot options are selected. If the problem persists, consider consulting Dell support or using a different installation method like Windows Installer from a USB drive.
