I have installed Windows 10 on my PC using Legacy mode(I checked Bios Mode in System Infomation, and it said Legacy). Now, after I found out the many advantages of UEFI mode, such as fast booting, secure boot, etc. etc. I want my machine work with UEFI mode.
Do I need to install it again in UEFI mode? I dont want to do this because I found out from googling it that the hard drive must be wiped completely to change hard drive system from MBR to GPT to make it run in UEFI mode.
What if I directly switch to UEFI mode(without reinstalling)? Will it work without complications?
I just tried to change that option in the bios, by curiosity (no idea what it does). The starting logo is a little smaller, but I don't see any difference on Windows 10. I wonder what it changes (in addition to the way the device boot). – JinSnow – 2019-06-06T14:23:38.627
