Repair Startup in Win 7

Repair startup issues in Windows 7

INTRODUCTION: We can use the Bootrec.exe tool in the Windows Recovery Environment (Windows RE) to troubleshoot and repair the following items in Windows Vista or Windows 7:

• A master boot record (MBR)

• A boot sector

• A Boot Configuration Data (BCD) store

Note: When we are troubleshooting startup issues by using the Windows RE, we should first try the Startup Repair option in the System Recovery Options dialog box. If the Startup Repair option does not resolve the issue, or if we must troubleshoot more steps manually, use the Bootrec.exe tool.

MORE INFORMATION: To run the Bootrec.exe tool, we must start Windows RE. To do this, follow these steps:

1.                Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.

2.                Press a key when you are prompted.

3.                Select a language, a time, a currency, a keyboard or an input method, and then click Next.

4.                Click Repair your computer.

5.                Click the operating system that we want to repair, and then click Next.

6.                In the System Recovery Options dialog box, click Command Prompt.

7.                Type Bootrec.exe, and then press ENTER.

Note: To start the computer from the Windows Vista or Windows 7 DVD, the computer must be configured to start from the DVD drive. For more information about how to configure the computer to start from the DVD drive, see the documentation that is included with the computer or contact the computer manufacturer.

Bootrec.exe options: The Bootrec.exe tool supports the following options. Use the option that is appropriate for our situation.

Note: Use the Bootrec.exe tool to troubleshoot "Bootmgr Is Missing" issue. If rebuilding the BCD does not resolve the startup issue, we can export and delete the BCD, and then run this option again. By doing this, we make sure that the BCD is completely rebuilt.

To do this, type the following commands at the Windows RE command prompt:

• bcdedit /export C:\BCD_Backup

• c:

• cd boot

• attrib bcd -s -h -r

• ren c:\boot\bcd bcd.old

• bootrec /RebuildBcd

/FixMbr

The /FixMbr option writes a Windows 7 or Windows Vista-compatible MBR to the system partition. This option does not overwrite the existing partition table. Use this option when we must resolve MBR corruption issues, or when we have to remove non-standard code from the MBR.

/FixBoot

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

• The boot sector has been replaced with a non-standard Windows Vista or Windows 7 boot sector.

• The boot sector is damaged.

• An earlier Windows operating system has been installed after Windows Vista or Windows 7 was installed. In this scenario, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).

/ScanOs

The /ScanOs option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista or Windows 7 installations that the Boot Manager menu does not list.

/RebuildBcd

The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option lets we select the installations that we want to add to the BCD store. Use this option when we must completely rebuild the BCD.

Set Timezone Commandline

Set timezone using configuration file

      The timezone configuration file “localtime” is located into “/etc/”directory. It is a symbolic link or a correct timezone file of “/usr/share/zoneinfo/Asia/Calcutta”. The “/usr/share/zoneinfo/” directory contains all pacific and country timezone file.

      Here the example to set the timezone to Calcutta (India) which is located in the Asia directory.

      Process to change timezone:

# cp /ect/localtime /etc/localtime.old

# cat /usr/share/zoneinfo/Asia/Calcutta > /etc/localtime

      or,

# ln -sf /usr/share/zoneinfo/Asia/Calcutta /etc/localtime

# date (Verify the changed timezone)

      Update time with ntp server using Internet. It will synchronize current time with NTP server.

# ntpdate pool.ntp.org

Set timezone using environment variable

      The “tzselect” command provide to select pacific and country location

# tzselect

      Select continent or ocean by prefix number

      Example: 5 for Asia, then select country 14 for India then press 1 for Yes. It display timezone configuration value. Now append the line in the “/etc/profile” file for make the changes permanently and then log out and log in again.

# vim /etc/profile

      Go to bottom line and enter “export TZ=Asia/Kolkata” without quot.

      :wq

# date (Verify the changed timezone)

      Note: For change timezone graphically, use “system-config-date” command and select timezone tab on the top of the window.
