Ubuntu 10.10 Dual booting problem

[spnoe]

I have Windows 7 on my hard disk and decided to dual boot with Ubuntu 10.10. I have installed this previously and not had a problem. However, this time Windows 7 is not showing up in the boot list sda. It is on the hard disk, I have checked using GParted. I have tried various fixes but nothing has worked.

On the partition it shows /dev/sda1 as ntfs System Reserved used 100 MIB
/dev/sda2 ntfs 515 Gib " 104.77 GIB
/dev/sda3 extended 415.47 Gib -
/dev/sda5 ext4 " 10.54 GIB

In the GParted at the top of the window where it shows the three partitions the box on the left /dev/sda2 on the right /dev/sda5
515.84 Gib 415.57 GiB

Could someone advise me on how I can get Grub to recognise Windows 7.

I did try to reinstall Ubuntu and I put the Grub / but this made no difference.

As you see I am not very experienced in the workings of Ubuntu.

Help gratefully received

Hi,
to help us get a better overview of the current situation, please do the following:

Boot the Ubuntu Live CD/USB. Choose the option "Try Ubuntu without any changes." Once the desktop loads come back here and do the following:

1. Download the boot info script. There is a link in my signature.
2. Once downloaded, move the boot info script to the desktop.
3. Open a terminal and run the command


sudo bash ~/Desktop/boot_info_script*.sh

This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here in a new post. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.
