A friend has asked me to put Windows 7 on to replace the preinstalled Win 8 Std that came with her Lenovo ideapad Z580 laptop. The BIOS is version 5FCN89WW and is set to UEFI boot but there is a legacy boot option available in its setup. I am unable to download the BIOS from lenovo nor am I able to dump it as the dump tools I tried would not read it. Nor would the SLIC toolkit I tried work either to determine if there already has a SLIC 2.1. I have just found BIOS version 2.3 after reading this post here, but have not had chance to test it yet as my friend has the laptop: forums.mydigitallife.net/threads/5866-LENOVO-%28IBM%29-Bioses-especially-Thinkpad/page521?p=718479&viewfull=1#post718479 I was able to use RW Everything and get a report though. Here: w*w.datafilehost.com/download-1211031b.html I am trying to detertmine if the BIOS already has a SLIC 2.1 so that I can install with a key and cert. And if not how i can insert one or use a modded BIOS if needed. If i am successful would i need to use legacy mode in the BIOS and remove the EFI partition. Apolgies if these questions seem niave but it is my first experience of UEFI. The disc and partition structure is presently like this (see pic below) Any help or advice would be gratefully received.
