No problem. I thought I'd be able to skip a step or two as I have a bootable Win PE disk and a USB DVD drive. It took a while to realise that the image was the whole drive.
I made the Windows 98 bootable memory stick from one of the first posts. I checked that booted to Win98 DOS. I then put the ODIN image on that disk. ODIN didn't like the USB Stick under W7, so I was able to boot the Windows PE and then use ODIN to dump your image onto a USB stick.
I then booted the USB stick into the Tech Guys image recovery mode, that seem to have put back both the hidden recovery and the main XP partitions complete with all the pre-installed software.
I'm just going though the windows updates etc etc.
So thanks again.
