I don’t know Tim if you are seeing these posted updates as I suspect between managing this support forum and working on your other products consumes a lot of your time, but I am posting my updates to mainly to help other users, as Winclone eventually got the job done.
I managed to figure out a solution to the stall at “Updating Legacy”, I simply closed Winclone and then installed the SSD (which was using an external eSATA dock) back into the Mac Pro tower. I restarted the Mac Pro, Bootrunner prompted me to select an OS; I clicked on the SSD with Win7 on it and to my delighted surprise, I booted successfully into Win7Ultimate. I then opened the Devices and Drivers window in Win7 and saw that there was an error message on the SSD, updated the driver, rebooted and everything worked fine. I also unchecked the defrag option within Win7.
If I had to do it all over again, I would make a backup of the 1TB HD with Winclone using “file-based’ imaging. I would NOT run sysprep, which I found problematic (fortunately, my original image was made of the HD before I ran sysprep and I was eventually able to restore my HD completely). I would then simply restore the 'file-based” image to the new SSD. Lastly, I should note that I never used the bootcamp Wizard to install the Apple-based drivers within Win7, as Mojave does not support Win7, only Win 10. I installed the Apple-drivers that work with Win7 directly for sound, keyboard etc. I can post a link to how to do this if anyone is interested (just reply to this thread).
I won’t be using Winclone as my backup solution for the SSD though, as all I really need is a Windows-based backup solution, given that Win7 resides on it’s own SSD and is not on a partition. For those interested, I purchased another license for Casper Backup software from Future Systems Solutions - which we use in our small home office for backup of a PC that runs our accounting software. This piece of software has been very reliable and has saved us a lot of headaches when hardware failures occurred on the PC. Backup times are a fraction of the time that it takes using Winclone which is a nice bonus. This is NOT a criticism of Winclone, whose design is focused on other factors besides cloning and which works well, in my previous experience, on Macbooks using separate partitions for the Mac OS and the Windows OS.
Bootrunner, BTW, is an excellent and reliable option for those looking to have full control of which OS they want to boot into. I have been using it daily for many months and it is solid.
