i'm currently using ubuntu10.10(/dev/sda10) and win 7 is installed on /dev/sda1.
during installation of ubuntu bootloader failed to install.so i had to do it manually later.but now the problem is that is does not recognise my win7 os.
i have tried many different suggestions given on this and many other forums but none worked.i even tried going back to grub(legacy) but that to didn't help.editing the menu.lst didn't work nor did the sudo update-grub did.
i also used the boot_info_script.it detects my win7 partition.if u want i'll attach it here.
the update grub command was running properly,but it didn't detect my win7
and currently using grub2 and the result.txt was when grub(legacy) was active
and here is my result.txt

Now that you have grub2 are you able to boot winsxp?
Wins7 recovery & boot are on sda1 it's possible you may have overwritten, even though there is anote saying that it's not.
The results.txt file you posted shows Grub2 in the mbr. The Grub2 grub.cfg file has no entry for windows. I don't know why the sudo os-prober and sudo update-grub commands didn't work. You might try running them again and posting the output. Someone may have an idea.
Did you try adding the entry manually in the 40_custom file.
Now that you know the partition on which windows is installed try adding the entry to 40_custom and update the grub, might work.
To reinstall grub to MBR. Boot using Live CD. Then
Code:
sudo mkdir /media/sda5
sudo mount /dev/sda5 /media/sda5
sudo grub-install --root-directory=/media/sda5 /dev/sda
Edit: added update-grub to get Win7 in the menu
sudo update-grub
Although the last update-grub command had to be done inside Ubuntu itself as it would not work on the live cd.
