I've used Acronis TI for several years/versions, used the Linux bootable disc, rebuilt hard drives, etc.  I also recommend it to my clients (and most are using it).  With my new build PC, for some reason, the Linux version of the Bootable rescure disc (2012 Plus Pack and 2013 versions) would not load correctly most of the time (no mouse control for one problem, somtimes it would just show errors) and when I could get it to initialize with mouse control I could select the backup that I wanted to use to restore from a USB connected hard drive but it would not allow selecting the target drive when trying to rebuild a disc from a backup.  I had to build a WinPE/Acronis bootable rescue disc to be able to rebuild/restore a drive from a backup.

I am not alone with this, according to response from one of the "guru's" on the Acronis forum.  It is a known issue with some hardware configurations.
