If I set the BIOS to how you have asked above, then Vista boots okay.
1 ch0 M. :WDC WD1002FAEX-00Y9A0 Vista Will boot to Vista
2 ch1 M. ST332062ONS (Formatted)
3 Bootable Add-in Cards (None)
ch0 is the drive with Vista installed. This is what is so confusing.
ch1 is the drive that has been formatted that once had Linux mint installed to.
I am under the impression that GRUB has been deleted from the formatted drive that Linux initially put there. So, if it was never installed to the Vista drive, I am wondering how, during a failed boot, GRUB gets a mention? I am only a novice so perhaps there is much more to this that I am unaware of.
Thank you for your response.
