I have the same problem. I'm trying to replace the hard disk in a Samsung R510 laptop with an OCZ Vertex 4. I've flashed the bios to the latest version, enabled AHCI mode in the BIOS.
I've tried with the SSD as both first and second boot priority in the boot list
I've tried no partition, creating a partition, creating & deleting
Nothing works - ever time it gets to the point where Win7-64 is ready to deploy to the drive, it gives the error saying it can't be installed.
