    Replace all C: letter with E: drive letter.

    Since the BCD store exists and lists a Windows installation, you'll first have to "remove" it manually and then try to rebuild it again.

    At the Command Prompt, type below command as shown and then press Enter:

    Code:
    E:
    At the Command Prompt, type below command as shown and then press Enter:

    Code:
    bcdedit /export E:\bcdbackup
    The bcdedit command is used here to export the BCD store as a file: bcdbackup. There's no need to specify a file extension.

    The command should return the following on screen:
    The operation completed successfully.

    Meaning the BCD export worked as expected.


    At this point, you need to adjust several file attributes for the BCD store so you can manipulate it. At the prompt, execute the attrib commands exactly like this:

    Code:
    attrib E:\boot\bcd -h -r -s
    What you just did with the attrib command was remove the hidden, read-only, and system attributes from the file bcd. Those attributes restricted the actions you could take on the file. Now that they're gone, you can manipulate the file more freely - specifically, rename it.

    To rename the BCD store, execute the ren command as shown:

    Code:
    ren E:\boot\bcd   bcd.old
    Now that the BCD store is renamed, you should now be able to successfully rebuild it.

    Try rebuilding the BCD again by executing the following, followed by Enter:

    Code:
    bootrec /scanos
    bootrec /rebuildbcd
    Restart your computer after rebuilding the BCD store.

    Sorry, what I meant was the E: drive is the installation disk (DVD), not the hard disk, so if I run that, I’ll only be fixing the BCD on the installation DVD.

    Is it safe to assume I can just copy the boot directory from the installation DVD onto the drive where Windows is at?

    You have to find BCD store on hard drive copying BCD store will not resolve the boot problem.
