Solution
This is a defect of Microsoft KB2919355 in the installation package. Hotfix KB2966870 is currently available at the following Web site.
Additional information
This problem mainly occurs on the system using an on-board LSI SAS2004 controller, but may also occur on other LSI controllers.
This problem occurs if the storage controller receives a memory allocation that starts on a 4 GB boundary. In this situation, the storage driver does not load. Therefore, the system does not detect the boot disk and returns the Stop error message that is mentioned in the "Symptoms" section.
This problem may not always occur in this situation. The problem is affected by the computer?s start-up process, the driver load sequence, and the memory allocation of the storage controller driver at startup.
