1. Windows Operating Systems

1.3 Microsoft command line tools

Boot Methods:If you fail to boot, first try to boot in Safe Mode. If it doesn't work, try booting to Last Known Good Configuration. If both fail, you can try using Recovery Console. You need to install the Recovery options for choosing this option on your Win 7 computer. If the option is not installed, you may get to the Recovery options by using the Win 7 installation CD ROM.

The file ntbtlog.txt file contains information collected if you choose to boot using "Boot Logging" startup option. The file shows which drivers are loaded and which have failed to load.

The Bootrec.exe tool supports the following options. Use the option that's appropriate for your situation.

1. /FixMbr :This option writes a Windows 7 or Windows Vista-compatible MBR to the system partition. It does not overwrite the existing partition table. Use this option when you must resolve MBR corruption issues, or when you have to remove nonstandard code from the MBR.

2. /FixBoot :This option writes a new boot sector to the system partition by using a boot sector that's compatible with Windows Vista or Windows 7. Use this option if one of the following conditions is true:

  • The boot sector was replaced with a nonstandard Windows Vista or Windows 7 boot sector.
  • The boot sector is damaged.
  • An earlier Windows operating system was installed after Windows Vista or Windows 7 was installed. In this situation, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).

3. /ScanOs : This option scans all disks for installations that are compatible with Windows 7.It also displays the entries that are currently not in the BCD store. Use this option when there are Windows 7 installations that the Boot Manager menu does not list.

4. /RebuildBcd :This option scans all disks for installations that are compatible with Windows 7.
