Ok, cheers Stuart. I did it yesterday so the latest 5.3 snapshot is already on the disk. I created a FAT32 partition which I can mount and save the new pbr file to ready to copy over into \C: drive on Windows7. I originally partitioned the disk using fdisk(1), rather than using Windows' crappy tool to "shrink" its partition, and did new installations of both OS's. I'll wait and see what surprises await then when I next upgrade :-)
