The task sequence has been suspended. Litetouch has encountered an Environment Error (Boot into WinPE!). If booting from a USB Flash Disk, please remove all drives before Retrying. Otherwise, ensure the hard disk is selected first in the boot order of the BIOS. Reboot WinPE (Close all windows) to resume.
This message is caused by running the Microsoft Deployment Toolkit boot CD after a previously interrupted attempt to install the operating system.
