CAUSE
There can be multiple causes for this problem. For details, please refer to Microsoft Knowledge Base Artircle 324103 titled "How to troubleshoot 'Stop 0x0000007B' errors in Windows XP". In the context of a BootManage Administrator driven unattended Windows installation, it is most likely that the problem is related to a missing, inappropriate or faulty third-party mass storage driver:
1. The Windows version does not contain a driver for the target system's mass storage host adapter.
2. An inappropriate or faulty third-party driver was added to the "textmode" part of the unattended Windows installation.
3. A third-party mass storage driver was added via "textmode", but the target PC's system disk requires the "standard" IDE driver.
