UEFI v2.3. 1 Corrigendum B The new UEFI, whose full name is "Unified Extensible Firmware Interface", is a standard describing a new type of interface in detail. This interface is used to automatically load the operating system from the pre-boot operating environment to the operating system, thus simplifying the startup process and saving time. Now this problem can be solved by brushing BIOS. In addition, if you don't support safe startup, you can also install WIN8, but the startup time is slightly slower. I brushed it.
