Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I deleted ubuntu as it stopped working and I couldn't find a solution on the internet. I planned to deleted ubuntu for now and reinstall it when I find my installation cd.

However, I didn't think about grub and then when I turn on the computer it said the grub partition cannot be found so I couldn't load into windows.

My recovery cd for windows vista doesn't have an option to recover/repair windows at all. So, seeing as there was nothing in the windows partition that I needed, I decided to do a full reinstall.

After installing the computer said to restart it. Once I restarted the computer I got the grub partition message once again.

I need help.

You should ask this on a windows forum... afaik it is something as fixmbr on the command line. –  Rinzwind Aug 6 '12 at 19:31
    
You reinstalled Windows or Ubuntu? What did you do to reinstall? How did you partition the disk? –  John S Gruber Aug 7 '12 at 4:06

With Vista and 7 ( they have the same bootloader ) you have to rewrite the MBR as usual and re-generate the small boot partition that takes care of all the steps for booting your Windows OS.

You have to boot from a CD, like a normal installation, or from a rescue CD, the important thing is that you have to start a prompt, once you have done that you have to follow this steps:

probably you want to focus on fixmbr and fixboot.
