Grub Error : Dual Booting

[spiderman5_]

Hello,
I'm a new user of Linux and Ubuntu. After trying Ubuntu from a CD I decided to install it so that I could have both windows and Linux. Installation went fine, it restarted the computer and I saw the menu asking me for the system to boot up. I selected Ubuntu and It booted fine. Then it said there were some updates to install and I updated. I believe I saw an error popped up but I wasn't sure. At the same time it asked me to restart the computer, which I did. However this time I didn't get the boot up menu. I got an error with the grub prompt and now I can't boot up either system. Can anyone help? I see similar threads but I'm not sure it the same solutions would apply to me. I didn't want to try something else that might complicate things.

Please provide step by step, as I said, I'm newbie to Linux.

Here are my results

Have a look here:

You had, and may still have a wubi install, you need to reload the mbr, use this wubi link, solution #1 is where you would start to get windows back.
http://ubuntuforums.org/showthread.php?t=1639198

This is the main problem, it should be a ms bootloader or lilo. In wubi never accept any grub-common, or grub-pc, or any grub updates.
Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #256 for /boot/grub.

Thanks for the suggestion. However, I think I must have done something wrong cause now I get the following error:

you link is dead add it with the paperclip in the reply panel.

You also need to give a description of what you actualy did. Also you may need to post the script again, look in my signature as to how to wrap it in code tags.

Thanks for all the help. I did try it one more type and it worked. I guess I was getting confused with the name of the drives. I followed the steps and now I have been able to see the boot up menu and I have booted up both systems successfully.

Thanks again.

Cool, so here is a vista recovery link if needed.
