USB Peripherals Not Working When Booting in Windows 10
If USB devices such as keyboards, mice, or external drives do not work during Windows 10 startup, the issue may be caused by incorrect BIOS settings, missing USB drivers, or outdated system firmware. First, try connecting the devices to different USB ports, especially USB 2.0 ports if available. Check BIOS settings and make sure USB support or legacy USB support is enabled. Updating chipset and USB drivers can also resolve the problem. If the issue occurs after a Windows update, use System Restore or reinstall the affected drivers. Keeping Windows and motherboard firmware updated helps prevent future USB boot-related problems.
