How do I install updates after fresh install of Windows?

I bought a Lenovo Legion Y520 laptop and it came with no OS. I tried installing windows 10 and got error code 8007025d, couldn't resolve it so i gave up. Now I installed fresh copy of Windows 7 pro (SSD wasn't showing up in the list so i just used HDD for now) and I have no drivers to even begin working. Since the laptop has no ODD I can't burn drivers and install them, i can only use USB flash drive. BUT! The laptop has no usb drivers either so it's not recognizing it when i input it (although it did when I used it to boot.iso)

Any help?

If you have internet access via an ethernet cable then you should be able to download the drivers from Lenovo if they ever supplied windows 7 drivers - Unfortunately you have downgraded to an unsupported operating system - This Lenovo was only supplied with windows 10
You may have to go back and do a clean install with windows 10 - or contact Lenovo for a recovery USB
