Win 8 hard drive no solution for install.wim file

The problem is as follows:
win8 official version is not like windows7 can use hard disk installation, because there is no install.wim file in ISO,
but install.esd file. Installation is not convenient?
The solution is as follows:
1) Enter the PE, format the C drive, copy the boot folder, sources folder, efi folder, bootmgr in the WIN8 directory to the C drive Under contents. Then exit and restart the computer. You can boot the installation with WIN8. Note that it is up to the installation partition, installed in the C drive, can not be formatted again!!
Extract the installation file to the root directory of the non-system disk.
2) into the PE, format an empty disk (if the drive letter is M), copy the
boot folder, sources folder, efi folder, bootmgr in the WIN8 directory to the M drive. Then modify the M disk as the first boot disk of the disk, that is, set the M disk as the active partition. Restart the computer to enter the normal installation mode.
The main points of the above two methods: copy the
boot folder, sources folder, efi folder, bootmgr in the WIN8 directory to an empty disk, and set the disk as the active partition, that is, as The first boot disk of the disk. Restart the computer to enter the normal installation mode.
3) Use NT6.
