Applies ToWindows 8.1 Enterprise Windows 8.1 Pro Windows 8.1 Windows RT 8.1

Symptoms

Assume that you have a computer that is running Windows 8.1 or Windows RT 8.1. The computer uses the Windows image file (WIM) boot feature, and the computer has 1 gigabyte (GB) RAM. In this situation, this issue occurs. 

Cause

This issue occurs because the Windows Boot Manager (Bootmgr.exe) allocates a large temporarily buffer in RAM to read the WIM file when the computer starts into Windows Recovery Environment (Windows RE). When the computer has 1 GB RAM, the allocation fails.
