			7z e sources/install.wim 1/Windows/Boot/EFI/bootmgfw.efi
	4.	mkdir efi/boot && mv bootmgfw.efi efi/boot/bootx64.efi
2.	Install

	2.	If windows gives "缺少需要的的CD/DVD设备驱动程序" error.Cancel install,remove and plugin usb key,then continue.[6]
		Make sure your usb has only one partition,or some extra cares must be
		taken.
	3.	When come to partition,fire up command prompt and execute diskpart
			list disk
			select disk 0 #assume this it what you want
			convert gpt # new gpt not work
			create partition efi size=512#grub2 requires it to be >= 200M.[7]
			create partition msr size=128
			create partition primary size=23552
