The difference between UEFI and Legacy and UEFI+Legacy matters needing attention when making a system
Original https://www.cnblogs.com/net5x/p/6850801.html
At present, some new notebooks only support UEFI mode, if [UEFI/Legacy] have it as win8 or do win7,win8 choose UEFI only supports 64-bit system and the disk partition must be gpt mode, traditional BIOS uses Int 13 interrupt to read the disk, each time can only read 64KB, very inefficient, and UEFI can read 1MB every time, load faster, do the system has to choose the installation version of the system.
