# ggRock Client Machine Blue Screen "IO1_INITIALIZATION_FAILED"

### **Problem**

Numerous ggRock Machines receive a Blue Screen of Death indicating "IO1_INITIALIZATION_FAILED".

### **Solution**

Remove internal hard drives from the Machines in your center if they are still installed.

### **Additional Information**

When a ggRock Machine boots via PXE, it mounts the System Image and Games image via iSCSI.

When this occurs, if a disk that matches the unique identifier of the System Image is mounted, unexpected behavior may occur including, but not limited to:

* Blue Screen of Death
* Inability to mount the System Image, resulting in the internal hard drive of the system being mounted instead meaning writebacks cannot be committed from the System Image.
* Inability to boot Machines.
