How to Repair Windows 7 Boot Manager

To Repair your Boot Manager you needed to do the following things:-

To run the Bootrec.exe tool, you 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 clickNext.
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, 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 your situation.

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

/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 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 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 you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.

After following the above i then ran the following from command prompt:

bootrec /fixmbr

then

bootrec /fixboot

This resolved the issue for me and allowed me to log on to the PC in its previous working state.  Great stuff.

Hope this works for you!

Install Windows XP in Dual Boot with Pre-Installed Windows 7

So you got your shiny new pre-installed Windows 7 computer over the holidays, but you want to have trusty XP standing by in a dual boot setup. Today we’ll walk through creating a new partition in Windows 7 then installing XP on it.

In this process we are going to shrink some free space on the Windows 7 hard drive to allocate toward a new partition. Make sure to take a moment and decide how much space to use for the XP partition. Make sure you have enough space on your hard drive for files you’ll be adding to each.

Create a New Partition

The first thing we need to do is create a new partition on the Windows 7 machine. Luckily we can do it without any 3rd party software. To begin, click on Start and type either partition or disk management into the search box and at the top of the menu click on Create and format hard disk partitions.

 
The Disk Management window opens, and from here we need to free up space on the (C:) drive Windows 7 is installed on. Right-click on the drive and select Shrink Volume.

 
 A window pops up showing the drive is being queried for available space.
 
 Now enter the amount of space you want to shrink the volume. You’re shown the total size of the disk and the amount of size that is available to shrink. In this example we’re freeing up 40GB of space.
 

 After the process completes you’ll see the new Unallocated space. Right-click that and select New Simple Volume.

 

The New Simple Volume Wizard launches which is a straight forward process. When you get to the Format Partition section, NTFS is selected by default as the file system and you can leave that as is. You might want to rename the Volume label something else like “XP Partition” so it’s easier to identify when installing XP. Also you’ll probably want to make sure to check Perform a Quick Format. 

 
After the format is complete you will see the new volume as a healthy partition listed.

 
 Now when you go into My Computer you’ll see the the new disk and notice that space has been taken away from the (C:) drive Windows 7 is installed on.

 

Install XP on the New Partition
Now that you know how to create a new partition on your Windows 7 machine, it’s time to install XP on it. Here we’re installing XP Professional on the new partition. Boot from the XP installation disk and start the install process.
 
 When it comes to choosing a partition, make sure you select the one you created using the steps above. In this example we made a 10GB partition for the XP install.

 
If the partition you created was already formatted as NTFS you can leave it, or you can choose the FAT file system if you want. 

Basically you continue through as if you were doing a clean install on any hard drive.
 

Create Boot Loader
Once installation of XP is successful you can now go through and install the latest Microsoft Updates and drivers. You will undoubtedly notice that the machine is booting directly into XP at this time. This is due to XP writing it’s bootloader over Windows 7’s. To get both XP and Windows 7 as an option at the boot screen you can use the free utility EasyBCD 1.72 or their new 2.0 Beta.
 

VistaBootPRO 3.3 (free version) will still work too which you can download here. VistaBootPRO is now called DualBootPRO and is free.

After getting the bootloader back you should see both XP and Windows 7 as options in the Windows Boot Manager.
