Windows CD or DVD for Lenovo when faced with broken website

If you don't care for the bundled rubbish that Lenovo put on their recovery media, just get the official Microsoft ISO file and bu it to DVD. If you can't do DVDs, you can create a bootable USB Key from the ISO using Rufus). Of course, you'll need a working inteet-coected PC to do this.

Activation is based on a licence that is permanently embedded within the laptop's BIOS, which is why this method works (it has done so since Windows 8.x).

As far as hardware drivers are conceed (for audio, graphics, etc.), Windows 10 will automatically download and install those when you coect to the inteet. Then, if you want some Lenovo-specific app, you can download said app from Lenovo's website later. Personally I stay away from those silly apps.

Have fun!
