Dual Boot - Can't see Win7 drive after removing other boot drive

My mobo (MSI P7N Diamond 780i SLI / 570i SLI) has a SATA raid controller providing 6 SATA interfaces

These are organised thus..

SATA 1 - [Partition 1 - Windows XP] [Partition2 - Windows 7 Beta (64bit)]
SATA 2 - OCZ Vertex - Windows 7 Home (64bit) Retail version
SATA 3 - Mirror A
SATA 4 - Mirror B
SATA 5 - Mirror A
SATA 6 - Mirror B

The system was originally running XP on SATA 1. I added a partition to SATA 1 and installed Windows 7 beta some weeks ago. The system dual booted to XP or Win 7 Beta fine.

I then added the OCZ Vertex drive and installed the Win 7 retail version, and I am able to dual boot to all three systems just fine.

However - I really want to do away with the XP and Win 7 Beta partitions and just run with the OCZ drive. However if I disconnect the drive from SATA 1 the system will not boot up. Can't find Ntldr or Bootmgr or something similar. I have changed the boot sequence in the BIOS to point at just the OCZ drive - but it just won't boot from it.

Any help would be appreciated.

In win7 make up the system repair disc (click start, type (without quotes) "system repair disc"), then remove the SATA 1 and boot off the CD you just made, and choose to repair startup problems.
