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.

To resolve this issue, we have released a hotfix for Windows 8.1 and Windows RT 8.1. We also have released an update rollup for Windows 8.1 and Windows RT 8.1. 

Before you install this hotfix, check the prerequisite of the hotfix.
