NT 4.0 primary partition failed. Replaced it, mirrored the contents. Disk 0 was primary, and Disk 1 was mirror. Could not boot unless I used a boot floppy. Ran fdisk /mbr to repair MBR. Upon rebooting from hard drive(successful), Disk 1 is now the primary, and Disk 0 is the mirror. I can’t break the mirror, or I lose everything. How can I repair this?
