startmanager-directing Winxp (/dev/sdc1) won't work

If you run:

sudo apt-get -y install os-prober; sudo os-prober; sudo update-grub

Does it get added ok?

You can't get "Windows booting first" persistent with StartupManager.
How to make Windows boot first permanently https://answers.launchpad.net/grub/+faq/1676

Thanks delance, that solved my question.

Thanks for a quick reply! Am a newby in Ubuntu - would you please explain exactly how I can implement your suggestion.

So it seems my FAQ is not clear enough!
To open a terminal, you can use Ctrl+Alt+T or Application->Accessories->Terminal
What explanation do you need ?

Thanks delance, that solved my question.

Sorry, am still getting used to launchpad.
I opened Terminal OK - pasted 1st line, hit enter, pasted 2nd line
Now it asks for my password - but I can't type anything at the prompt! Won't accept pasting the 3rd line.

Nothing is displayed when you enter password, even stars!
Could you reopen question. It is marked "Solved" currently.

Re setting Windows 1st in boot manager:
Have Terminal running. Pasted your follwing suggested code all in 1 line
 cd /etc/grub.d
    sudo mv 30_os-prober 09_os-prober
    sudo update-grub
The following line appears:
{studio} password for bumpy: []
How do I enter my password - it won't accept any keystrokes?

sudo doesn't give a visual feedback. This is to hide length. Just type the password and hit ENTER. It will work

Sorry - a typo error:
The following line appears:
[sudo] password for bumpy: []
How do I enter my password - it won't accept any keystrokes?

I did that, rebooted & windows is still on the bottom line.
Selected it & hit enter - it returns to the same menu - does not work - am back in Ubuntu

Could I edit the bootup screen to solve this?

Question:
Can I edit the Boot menu on startup to rectify this, & if so, how?

Please post result of:
    ls /etc/grub.d

It will be more complex! It means either Grub is badly configured or Windows boot is broken.

There is a standard script provided to analyse boot configuration. Could you download script at:
   http://sourceforge.net/projects/bootinfoscript/
Then in a terminal (Ctrl+Alt+T) run command:
    sudo bash ./boot_info_script055.sh
This will produce a file named: RESULTS.txt. Paste content of this file in http://paste.ubuntu.com/ and provide in this thread the link to Web page. Please don't post file directly in thread, else it will make thread difficult to read.

Try "fixboot" but NOT "fixmbr".

Downloaded script
ran terminal
Result:

bumpy@bumpy-desktop:~$ sudo bash ./boot_info_script055.sh
bash: ./boot_info_script055.sh: No such file or directory
bumpy@bumpy-desktop:~$

I presume I should run the script - how do I do this?

New name of file is: boot_info_script.sh
Check it by going inside folder.

http://bootinfoscript.sourceforge.net/ describe the commands to run.
Please search by yourself in Web page. I could have answered tomorrow morning!

Boot into any Linux based operating system, LiveCD or LiveUSB with an Internet connection.
Download the Boot Info Script
Extract the zip file to a directory of your choice.
Open a terminal (Applications -> Accessories -> Terminal in Gnome) and type :

  sudo bash [path/to/the/download_folder]/boot_info_script.sh
