I have not been able to make a Rescue CD that will boot for several weeks. Now, finally, I found out why - and have burned a good disk. The problem (after much reflection) occured about the time I updated the BIOS on my Dell Dimension 8400 PC from A05 to A06. Today, I checked the Dell website to see if I could flash back to Bios A05. What I found is that Dell has issued a new BIOS A07 - to correct "boot issues when USB devices with media readers are present." Since I do lots of digital photography, I have an USB connected card reader; and my USB connected HP-printer also has built-in card readers, too. Dell folks may want to check-out this link http://support.dell.com/support/dow...s&releaseid=R104588&formatcnt=1&fileid=135036 Anyway, after flashing the newest BIOS A07 for my computer, then burning a new Acronis Rescue Disk - - - WOW! The CD now boots just fine, and looks like it will restore images; though I haven't gone through all the steps yet. Moral of the story, perhaps for Acronis Tech also to know about: if your rescue disks won't boot, check your PC maker's website to see if you have their latest version of BIOS.
