Computer boot from Acronis Archive.

Hello!
I have Acronis True Image Home 10 on Windows XP SP2. I know that it's old...
Yesterday my computer booted from archive spontaneously. When I manually select from which hard drive boot, everything runs well. But then I try restart computer and it restore old archive again.
Please, help me!
Thanks=)

I'm sorry. Problem resolved. In BIOS I make correct priority to boot from hard drives. I don't know why, but earlier computer boots good.
