Gotcha. To the best of my knowledge, no. You should be able to toggle Secure Boot on and off as needed. For example, I sometimes need or want to use a USB flash drive to boot a Linux distro. Without getting into gory details of Secure Boot, it's generally necessary to disable it to do this. When I'm done with that, I re-enable Secure Boot and boot into Windows.MS Instructions for Disabling and Re-EnablingDisabling Secure Boot | Microsoft Docs
I Upgraded to Win 11 when it was first available. I turned on TPM 2.0 to install it. Everything has been working OK. I just realized that "secure boot" was never turned on after installing Win 11. Should it be on? If I do turn it on, would I still be able to do a clean install of Win 11 if I need to sometime in the future? Or would I have to turn it off again? Thanks
