First, this is not a WinPE production tutorial.
Before my own computer with the build 10074, helpless input method bug can't ignore ... Just see the 10030, so install 10030, here to record the process for installation later.
PC recommended to install Homeedition, not pro version, Pro version is Tablet PC dual use.
Required: A USB flash drive (formatted), a winpexxx.iso, UltraISO software, Winntsetup 3.8 (not required, preferably ready), partition Assistant in WinPE (not required)
1. Make USB boot disk, http://www.cr173.com/html/12141_1.html, and then BIOS setup USB drive to start first.
2. After booting, enter WinPE, generally have Windows Installer, open is actually winntsetup older version. If partitioning is required, you can use the partition assistant, or you can use the Diskgenius that WinPE typically provides
3. After the partition operation is complete, you can install Windows with Winntsetup http://www.windows10.pro/winntsetup-install-win10/
4. Note that when you restart, remember to unplug the USB flash drive or change to a hard disk boot priority.
Use USB stick to start WinPE installation WINDOWS10 preview
