I am not understanding the issue.....I just wincloned my W7 a couple weeks ago and it works fine.
-1st, I used Winclone to image W-7, saved it to desktop.
-Used Superduper to clone old hard drive (and that will include the saved image of winclone on the desktop).
-The only prep for the new hard drive is make sure it is only one partition, hfs +, GUID.
-Install new cloned HD to my mac.
-I made the W7 partition using Bootcamp. I only used it for making the partion and then exited.
-Restore W7 image using winclone, to the bootcamp partition.
No problems or issues. I used the last winclone version 2.2.
I made no modifications to my Snow Leopard OS or Mac or did anything other than what I said above. Winclone 2.2 does work with SL.
Just use the free SuperDuper or CCC for your mac.
