I thought I would upgrade to Vista as I have a pukka Vista Business upgrade - that booted, entered the legitimate code, and then was told ' using that number you must upgrade from your current operating system - aaarrghh!!!

So at least the system is booting from the CD drive.

But not from the ubcd4win cd's.

Sadly I cannot find my XP cd - I have the sleeve with product key, but not the disk frown Goodness knows where that went.

I think my only option is to go out and buy another laptop and try and find a way to mount my current HDD on that system. Although my existing laptop is T7500 with 2GB of Ram, so I doubt I will get a system that is much better.

I have another copy of Vista that isn't an upgrade, but that is a 64bit version so no good.

All good fun....
