Hello, Thank you all for all those great responses, I'm definitely grateful.
Dan, I followed your instructions, please tell me if this is the expected output, I'll try to transcribe everything: Network controller: Intel Corporation Wireless 8260 (rev 3a) Would you please tell me what to do next? David, I found that file too, actually I found four or five of them, but not all. I put them on the USB installation drive but the installer kept asking for them. I'm sorry, I should have been more precise when I said that Google didn't help me much. What I meant was: it only found a few of those files and they were ignored by the installer. Digital thanks to all those who took a moment to write back! Vlad.
