Windows Image Backup sees my drive G as a sytem drive same as C:

was able to do a back in less then 10 minutes

What did you image?

I just recently learned a simple solution. It works well. Go into disk management and remove any unwanted drive letters that you cannot de-select. Then you must close Disk Manager. Then start your Windows image. Those other pesky drives won't be on the automatic list.
While it's running, you can go back into disk management and add the disk letter back. Usually the drives are not included in Windows automatic selection after that.
FYI, I recently had to recover from a system crash, Windows Image Restore failed, Aconic True Image failed, only Macruim Reflect Free did its job.
