After reading this forum quite a bit, I've finally discovered the "acpi=off" trick, without which Acronis Startup Recovery Manager won't work at all on this computer. (That really should have been in the manual, or better yet, an option in the TrueImage program.) If I press F11 and enter the setting manually at the boot menu, it works fine. However, I can't figure out how to make it automatically default to "acpi=off". I've tried editing the kernel line in Program Files\Acronis\TrueImageHome\f11.cfg, and then disabling and reenabling the Startup Recovery Manager, but this has no effect. Am I editing the wrong file? How can I make the Startup Recovery Manager default to "acpi=off" every time I use it? I'm using TrueImage build 3567.
