    Default Nothing works after installing windows 7

    So basically i downgraded my windows from 10 to 7. And nothing is working now. Usb doesnt recognise. So i cant install anything, any drives to connect to internet or anything. No ethernet port, no cd rom. Its inspiron 15-5578. I tried tweeking bios, the current version is 1.21.1. Maybe i need to upgrade bios to be able to downgrade usb ports to 2.0 or something. I have an idea, but not sure really how to make this work. Can someone help me out?

    Usually that happened when you downgrade your OS, but it should be supported with installers on the laptop/pc manufacturer website, just go to their website and look for your model then check the download software you will need to choose a OS version for it so you can get the right software. Hope this helps

    Check your hardware specs. Repair Windows OS using Installation Disk. Update all device drivers.
