Yes, I'm convinced the Vista drive doesn't currenly have it's own MBR so if the 'DVD repair' option fixes that then that will be perfect. As for the XP drive I no longer wish to use this, instead I wish to perform an LLF on it and use it as a mirror drive for the Vista drive, once it runs independantly.

I do not wish to reinstall the OS on my Vista drive so I do need to be sure/confident that the 'DVD repair with cmd options will fix its MBR, can you confirm that my understanding is correct in that it will based on the knowledge that the XP drive will no longer exist. Thanks again.
