Hi, I just happened to watch my pc's bios today and I saw that it was in Legacy mode, not UEFI, after some googling of what it is, I came to know that legacy is outdated and i should have installed my OS in UEFI mode. Can you tell me exactly what the two modes are and the advantages of UEFI over LEGACY and how to actually install an OS in UEFI rather than LEGACY. I'm just confused
