ubuntu 12.04 will not boot windows failed to start

I installed Ubuntu 12.04 on its own HDD (Windows Vista is installed on a separate HDD). When I restart the computer and select Ubuntu to boot, I get the error "Windows failed to start" along with a reference to "\ubuntu\winboot\wubildr.mbr".

If I select Windows Vista to boot, Vista starts up just fine.

I used to have Ubuntu 9.10 installed and was able to successfully dual boot into either OS.

I did not use wubi for the 12.04 installation (though I may have for the 9.10 install -- don't recall).

Thanks

    Problem solved.

    I had just installed Ubuntu 12.04 and had restarted to test the installation. That's when I got the the usual old OS boot selection screen (not GRUB). That's where selecting Ubuntu would result in the "Windows failed to start" error.

    I got things running by running Ubuntu's Boot-Repair utility which is explained in detail at

    https://help.ubuntu.com/community/Boot-Repair

    Now when I restart, a new Grub screen appears that presents Ubuntu or Vista boot choices, and I can successfully boot either OS from there.

    However, if I select Vista, the next screen is the old (Windows-generated) OS boot selection screen mentioned above. Ubuntu is still a choice, and selecting it still results in the "Windows failed to start" error. I just ignore the "Ubuntu" option and choose "Windows" (or do nothing and wait for Windows to be booted by default.)

    You can edit the sub menu using a program called grub customizer. Search it in the software centre.
