To do various tasks with Acronis Disk Director Suite a reboot occurs and the interface is the bootscreen. Not being able to see what's happening is a tad painful (understatement ). I unfortunately found this out the hard way (watching my computer sit on the boot screen for 3 hours doing nothing, afraid to turn it off as the hd light was working. It may handy to note this in the install warnings. Cheers for a great app
