JSI Tip 2039. What is the difference between a Fast Repair and a Manual Repair?

When you run a repair, you are offered two choices, Fast Repair or Manual Repair.

When you boot the installation media, you can press R to use the Emergency Repair process. You will then press M for a Manual Repair or F for a Fast Repair.

During a Manual Repair, you can select/deselect the following:

\[X\]  Inspect startup environment
\[X\]  Verify Windows 2000 system files
\[X\]  Inspect Boot Sector
     Continue <perform selected tasks>
Inspect Startup Environment checks the ARC path against the Setup.log file on the ERD or %SystemRoot%\Repair folder. The Setup.log files contains:
TargetDirectory = "\WINNT"
TargetDevice = "\Device\Harddisk1\Partition1"
SystemPartitionDirectory = "\"
SystemPartition = "\Device\Harddisk1\Partition1" 
With this data, the ARC path can be corrected or a missing boot.ini can be created.

Verify Windows 2000 System Files checks all the Windows 2000 files on the System/Boot partition against the Setup.log CRC value for each file. If the file is missing or corrupt, you are prompted to replace it.

NOTE: The optional NTbootdd.sys is not checked.

Inspect Boot Sector repairs the active system partition boot sector and reinstalls the boot loader. If a non-Windows 2000 boot sector is found on a FAT or FAT32 system partition, the Bootsect.dos file is created and a C:\ = "Microsoft Windows" is added to boot.ini.

NOTE: There is no registry repair option with Manual.

The Fast Repair option does all of the Manual Repair options and checks the SAM, SECURITY, SYSTEM, and SOFTWARE registry hives for corruption.

If a hive is missing or corrupt, it is replaced from the %SystemRoot%\Repair folder.

If a hive is replaced, your system has some updated hives and some original hives. You must do one of the following:

1. Restore the System State.

2. Use the Recovery Console to replace the hive with a more recent copy, as from %SystemRoot%\Repair\Backup (if you checked Backup the Registry while creating a recent ERD).

Both repair options will check the file system integrity on the boot and system partition. If a correction is made, you will need to restart and choose Repair again.

Neither option checks %SystemRoot%\System32\Config.nt or %SystemRoot%\System32\Autoexec.nt.

If you don't have a CD-ROM installed, use the Recovery Console to simulate a repair, or use a technique like in tip 0563.
