You\'re right! Windows Disk Management was telling me that both partitions were 100% free but when I look at it on Partition Wizard it shows that there is indeed stuff there. I was going to try what you suggested but F8 is still not working for me (I see from Google that this is not an uncommon problem!). To be honest I\'ve had way more than enough hassle with this already and I\'m inclined to just leave things be as I now have a working, useable set up again. The laptop that the Windows 7 upgrade was purchased for is now defunct, having been replaced with a new Windows 8 machine. Are you sure that I can\'t just leave it be on this one?
