Okay, I can only get as far as downloading imgburn on those instructions Barry, because I'm working on a Mac and it's a .exe file that just brings up a notepad file of gobbledygook.
As you're on a Mac, you don't need imgburn at all, sorry should have clarified, that's just to burn it. Download this link:
http://pogostick.net/~pnh/ntpasswd/cd110511.zip (Edit: you have to open this first, so you have the ISO file.)
Then burn it using toast. Right click, open with, Toast. (Not meaning to be patronising, apologies if seems that way.
)
Then insert the new burnt CD in the Windows Laptop and follow instructions. (YouTube vid from 4:10 or so onwards should help with instructions.)
