You know, I'm having the same issue, and yes, it is an Optiplex 745 with the SATA drives. My problem started with trying to boot with a Ghost bootable CD (don't remember the error text), but now I'm trying to use the Ghost Console, and the machine will not boot to the virtual partition. The error I am getting is "Failed to reboot client to recovery partition".
The NIC is a Broadcom NetExtreme 57, and it appears the problem is occuring after the startup file is processing the netbind commands, but I really can't tell because it flashes by so fast, then just reboots the computer. Looks like about 12-14 lines of commands are being processed.
The machine has Vista Ultima loaded, but I'm not sure if the problem is related to that.
The other thing to note is that the first DVD drive was a Philips DVD-Rom (no model no.) and the drive I currently have installed is a Toshiba DVD Writer TS-H653.
One thing that would help would be if I could find the actual startup file that is being processed. Then I could see where the failure is occurring. But, any ideas where I could start troubleshooting this at?
