Once you can boot into installer, you can run the mbr recovery. <div class="gmail_quote">On Sat, Oct 1, 2011 at 1:54 AM, MFauzilkamil Zainuddin <<a href="mailto:apogee@ubuntu.com">apogee@ubuntu.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">After you have done the recovery, try to boot your PC without your 500GB hdd. If your windows 7 can boot (without the 500GB hdd), now you know that your win7 and its MBR are intact.
