I had a drive fail mechanically and now need to boot from the mirrored drive. I’m not having much luck. I removed the failed drive and put the mirrored drive in place of the failed drive.
When I try to boot from the mirrored drive I received the message "NO OPERATING SYSTEM FOUND". Is there something I am doing wrong? How do I get this machine to boot from the mirror?

Thanks in advance.

1. Make sure that mirrored drive hardware address is correct. For example if you had SCSI drive, ID 1, and moved it phisically to the place of the failed drive, it would not help you because SCSI ID is usually set by jumpers on the drive.

2. Perhaps your Master Boot Record (MBR) on mirrored disk is not correct, or the partition from which you try to boot is not marked as active.

3. Try booting with boot floppy.
To prepare boot floppy you need to:
a) format floppy on Win2000 system (NOT Win9x/Me).
b) Copy following files from working Windows 2000 system to floppy:
BOOT.INI
NTLDR
NTDETECT.COM
c) Edit BOOT.INI file so that entry in the [operating systems] section points to your boot disk and partition and directory.

Not limited to scsi... check if ide too, also if it wasn't fdisked (or whatever partioning proggy u use) to be active, of course don't change it now. Hopefully all the data is there and you can transfer it over to a properly partioned and active drive after booting with a floppy as above.
Savatovic got it right. :) I just thought i'd add a couple real minor points just in case....
