Mirroring Prevents Pre-Installing the Recovery Console

The Windows Recovery Console is used to facilitate repairing an unbootable computer. It requires the Windows installation media (the four Setup disks or the CD-ROM). The Recovery Console can be pre-installed by running the winnt32 /cmdcons command from the Windows installation CD-ROM to place the files on the local hard disk. This option requires approximately 7 megabytes (MB) of disk space on the system partition.

When your system partition (containing the Ntldr, Ntdetect.com, and Boot.ini files) is part of a Windows basic or dynamic disk software mirror, you cannot pre-install the Recovery Console. If you try to pre-install the Recovery Console with the winnt32 /cmdcons command, you receive the following error message:
No valid system partitions were found, Setup is unable to continue.
The winnt32 /cmdcons command performs the same system checks as a "clean" installation. A clean installation of Windows is not allowed on a mirrored system partition.

If you want the Recovery Console pre-installed on a mirrored system partition to help facilitate a repair, you must break the mirror, install the Recovery Console, then re-establish the mirror.

NOTE: If you are using legacy basic disk mirroring, you should not break the mirror unless you plan to upgrade the disk from basic to dynamic. Legacy disk mirrors cannot be re-created in Windows; only dynamic disk mirrors can be created.

Pre-installing the Recovery Console on a computer running Microsoft Windows NT 4.0 is allowed, but you must break the mirror, install the Recovery Console, re-establish the mirror, and then upgrade to Windows 2000 or Windows XP. This process retains your legacy basic disk mirroring.
