Welcome to the future. Ever since 2000, EFI (Extensible Firmware Interface) has struggled to replace the decades-old BIOS, and now, some 13 years later, it’s finally really here. More than ever before, new computers, laptops, notebooks, and other computing devices are being shipped that use an entirely new and very much different technology as the foundation that powers the actual hardware, sitting between your motherboard/CPU and the operating system.
EFI is pretty nifty and very powerful, and opens a lot of new and exciting possibilities for your computer. It lets Windows theoretically boot faster than ever before, and can protect your computer against malware and viruses thanks to enhanced security features like signed bootloaders. And for Windows users, EFI means GPT (GUID Partition Table) instead of MBR (Master Boot Record). Abbreviations got you confused? Don’t worry – it just means that your computer now supports hard disks that are bigger than ever before (more than 2TiB in size!).
