I am new here, and I come... with a problem! So here's the deal:
I've been wanting to set up a dual boot with Lubuntu and Windows 10, Windows 10 being the operating system I currently have on my laptop, a Lenovo Z575. To do this, I leaned I needed to disable Secure Boot, so that it will be able to install (I'm very new at this, I may be saying this all wrong.) I looked around online, and followed the common instructions of
1) Shift+Press restart from the start menu
2) I then went to Troubleshoot
3) I went to Advanced Options
4) In this menu, there was supposed to be a setting for UEFI Firmware Settings.
There was not this option, in its place there is Startup Options. After selecting this option, I was not presented with the menu to disable Secure Boot. So I then tried looking around in the BIOS menu, by restarting the laptop and pressing f2 while it booted. I went down to the security menu, and Secure Boot was not listed there, or anywhere in the BIOS at all!
I would very much appreciate if someone could help me figure this out... It has got me rather flabbergasted.
