Type '''''BOOTREC /FIXMBR''' ''and hit <'''Enter'''>.

This command will attempt to fix any corruption issues with the master boot record.  If all goes well, you should see ''The operation completed successfully.''

Next, type '''''BOOTREC /FIXBOOT''''' then hit <'''Enter'''>.

This command will attempt to write a new boot sector on the hard disk if Windows detects damage. Usually, this happens in cases where an older version of Windows was installed, or a non-compatible operating system such as Linux was installed.

If you are seeing an error such as ''Boot Manager is Missing'', then the '''''BOOTREC /RebuildBcd''''' command might be able to fix it. This operation can also restore boot entries for older versions of Windows if you have a dual boot configuration.

If '''''BOOTREC'' ''/RebuildBcd''''' does not work, then Microsoft recommends you back up your BCD (Boot Configuration Data) store, then run the '''''BOOTREC'' ''/RebuildBcd''''' command again. Here is how you do it.  Type each command then hit <Enter>:

·                     '''bcdedit /export C:\BCD_Backup'''

·                     '''c:'''

·                     '''cd boot'''

·                     '''attrib bcd -s -h -r'''

·                     '''ren c:\boot\bcd bcd.old'''

·                     '''bootrec /RebuildBcd'''
