Angels have the Phone Box
Here's another story. I had a someone's Dell W8 machine to upgrade to W10. It had gone through the W8>W8.1 upgrade, and now W10. There were something like half a dozen partitions by the time all was said and done. So, after upgrading to W10, I imaged the C partition, clean installed W10, then in Macrium Restore mode, I dragged the C partition from the image back onto the system drive, and voilą! All the programs and data were back, and all the useless partitions were gone (including the Dell recovery partition).
