Booting from Mirror

[Shift Support]

I have a server which boot Win 2003 from the SAN, now wish to boot it from local disk. I have mirrored the OS to the local disk. Then when I remove the SAN disk and try to boot from the local mirror it fails. Seems like it cannot determine that the local disk is bootable. Have tried FDISK / MBR, Fdisk shows it has a partition, tried booting from a recovery floppy, ensured that the boot.ini is correct, even recovery console will not correct it. Has anybody seen a procedure to boot from a mirror?

Have you changed any BIOS settings? Sounds to me like the server is still trying to boot from the HBA.

The bios settings were changed to it would boot from the loca disk. Error displayed is something to the effect that the HD is corrupt.
