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:
- Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.
- Press a key when you are prompted.
- Select a language, a time, a currency, a keyboard or an input method, and then clickNext.
- Click Repair your computer.
- Click the operating system that you want to repair, and then click Next.
- In the System Recovery Options dialog box, click Command Prompt.
- Type Bootrec.exe, and then press ENTER.
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
- 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).
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!
