Fix Vista’s MBR

Vista’s Master Boot Record

Here is a good tool to know incase you need to repair your Master Boot Record

Applies to all versions of Vista

Windows Recovery Environment (Windows RE)

 

If you’re like many who received Vista installed on a new machine. Then you know the troubles of not getting the install or Recovery Disk from HP, Dell or your favorite vender.

Your in Luck

Here is a downloadable 120 Mb standard ISO format Recovery Disk, for both the x86 and x64 Bit versions of Vista.

Windows-Vista-Recovery-Disc

Note: This is only a Recovery Disk, not a full Vista Install Disk


You can use the Bootrec.exe tool in the Windows Recovery Environment (Windows RE) to troubleshoot and repair the following items in Windows Vista:
* A master boot record (MBR)
* A boot sector
* A Boot Configuration Data (BCD) store
Note When you are troubleshooting startup issues by using the Windows RE, you 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 you must troubleshoot more steps manually, use the Bootrec.exe tool.


Note: If you are running a RAID array, if this does not help and you are receiving errors. Check in your BIOS and make sure the BIOS did not convert back to IDE. Vista needs to see the complete MBR, In a RAID setup the MBR is split between two drives.


To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:
1. Put your Windows Vista 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 you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type “Bootrec.exe”, (without the quotes) and then press ENTER.


Note: To start the computer from your Windows Vista DVD, your computer must be configured to start from the DVD drive

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

/FixMbr
The /FixMbr option writes a Windows Vista-compatible MBR to the system partition. This option does not overwrite the existing partition table. Use this option when you must resolve MBR corruption issues, or when you 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. Use this option if one of the following conditions is true.
* The boot sector has been replaced with a non-standard Windows Vista boot sector.
* The boot sector is damaged.
* An earlier Windows operating system has been installed after Windows Vista 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. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista installations that the Boot Manager menu does not list.

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

Note: If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run this option again. By doing this, you 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
