|Error code: 0x000000ED|
The kernel mode I/O subsystem attempted to mount the boot volume and it failed. This error might also occur during an upgrade to Windows XP Professional on systems that use higher throughput ATA disks or controllers with incorrect cabling. For example, you use a standard 40-wire connector cable to connect a UDMA drive to the controller instead of the required 80-wire, 40-pin cable. This problem may also appear if the file system is damaged, therefore it cannot be mounted. Running the "chkdsk /r" command from Recovery Console might solve this problem.
As M892000 states, this issue occurs with some versions of the Pqv2i.sys driver. The Pqv2i.sys driver is included with the V2i Protector 2.0 program from Symantec. In this case, update the driver to resolve the problem.
