In my Laptop BIOS, I saw Boot Option has two Choose, "UEFI and LEGACY"
I wonder, what are they?
When i tried to get into BIOS and Change BOOT Mode to "UEFI"
My computer won't boot and BIOS message alert
"Default Boot Device missiong or Boot failed.
But when i change Boot Mode in BIOS to LEGACY
I can boot Windows As normally.
Could you explain me what is UEFI and LEGACY?
What they are using for?
