Consider the following scenario. You have a Windows Vista-based computer. An image that the manufacturer created was used to install Windows Vista. The manufacturer used the System Preparation (Sysprep) tool to create this image. The computer’s hard disk drive is partitioned into two or more partitions. The partition on which Windows Vista is installed is larger than 40 gigabytes (GB). Additionally, the size of the partition is a multiple of 4 GB. You run Windows Vista Setup. You delete the existing partition on which Windows Vista is installed. You try to create a new partition. In this scenario, you may receive an error message that resembles the following:

Windows installation encountered an unexpected error. Verify that the installation sources are accessible, and restart the installation. Error code: 0xE0000100
