As I recall from prior discussions with Acronis tech support, but maybe only certain setups, they will overwrite the MBR bootstrap area with their own bootstrap code which is used for recovery (i.e., to perform restores before and without requiring the load of the OS). I need the the MBR bootstrap area for a multiboot manager to let me load different operating systems that reside in separate partitions. Some programs that want the MBR bootstrap area will allow chaining of the bootstrap programs. That is, they will move out the old bootstrap program to some holding area so they can slide in their own bootstrap program, and when their bootstrap program is finished then it loads and passes control to the original bootstrap program. I've only seen one or two programs like this that are polite in handling and supporting bootstrap programs from other parties. Usually if a product wants the MBR bootstrap area, it just rudely steps atop of whatever is there. Does Acronis do the same thing? Can I use Acronis without it stepping atop the MBR bootstrap area (first 446 bytes of the first sector in the 'hidden' track on the first physically detected hard drive found by the BIOS)? What functionality do I lose if I don't use Acronis' own bootstrap program? Can that functionality be equivalenced by using their install CD or a bootable recovery CD that their program creates? If major functionality is lost because I cannot let Acronis usurp the MBR bootstrap area then I'll have to look elsewhere for viable backup and imaging solutions.
