I already did a clean install of Win10 on my Dell laptop which does seem to support UEFI mode when I went through the BIOS setup screen. My current BIOS setup is using the Legacy BIOS mode.
My question is, if I do decide to enable UEFI with Secure Boot, will I need to reinstall Win10 again?
If that's the case, then will I need to enable this UEFI before installing or after installing Win10?
I installed Win10 using the Media Creation Tool.
So does this mean that I have to start right from scratch again in order to use the UEFI with Secure Boot?
In in other words, do I need to create another Media Creation Tool for my bootable USB flash drive and reinstall Win10 all over again?
Or, can I just go into my BIOS setup and select UEFI with Secure Boot without reinstalling Windows again?
Please explain this.
