Hi, I installed Windows 7 on Drive C. I have a 2nd hard drive D. The 2nd hard drive has a MBR from an XP installation that seems to be interfering with the boot of Windows 7. I don't have XP installed anywhere. I have folders/files on D that I cannot lose. Please can someone advise me on how to delete the MBR on D: without affecting the files on it? Thanks in advance for any help.
