I have a Gateway laptop M series that I upgraded to Windows 7 a few years back (o.g. Vista) has run beautifully ever sense. Recently installed Win8 fresh. Error code OxcOOOOOe9 became the issue. Start up repair was performed several times with no resolve. Used cmd to perform MBR fixes including fix mbr, bootrec.exc, and other fixes found on this site. Nothing seems to resolve the issue. I gave up and was about to call it quits, under the assumption the hdd was gone. One day I decided to throw a fresh copy of Ubuntu on it for laughs ( I am currently getting my certs in networking and linux+) it works flawlessly. Strange to me although I understand there is a difference with grub and mbr. If there are any suggestions, I would be most thankful.
I should add that I am now just trying to reinstall 7. I have played with 8 on a different PC and would rather stick with the former.
