How to change boot mirrored disk

Ian3 66 Reputation points

My PC Disk0 has C: and D: partitions. Windows 7 installed on C:.

I add a mirror disk on Disk1. So C: and D: are both mirrored.

Disk0 is dying and need to replaced. After Removing the mirror, the machine still can boot from Disk0 but not Disk1.

How do I boot from Disk1 so I can add another mirror disk as protection. Thanks Ian
