What are the conditions for uefi to start?

I just want to tell you the operation method simply:

First, when installing, choose F 1 1 or F 12. Different notebooks are different. In short, just pop up the boot mode directly, and choose the U disk installation system of UEF USB (provided that the system has been mirrored on the U disk).

Second, format the hard disk in GPT mode when customizing the installation. The original win8 system can be formatted like this. How to format it specifically, please ask Baidu, because it is more complicated to say, you can check it with Baidu, and the picture is simple.

Finally, the general process of installing the system is not as complicated as you said, nor as official as they answered.

If it is installed, how can I confirm it? Please check my installation drawing and check it in Control Panel, Computer Management/Disk Management. The picture is as follows:

Look at the second item, there is an EFI system partition, which means it is successful.

Finally, an original system of Win8 or 8. 1 is made into a USB flash drive to start without other tools. I didn't answer until you got a high score in the exam. I don't want to generalize.
