I've tried making four different boot disks and none of them work. During the startup the boot disk is ignored and Windows starts instead. I know my bios is set up properly because I can boot from other disks. The most recent attempt to create and test an Acronis recovery boot disk created an error message every time Windows XP started. The error was a pop-up window titled WINDOWS - NO DISK and the error was "Exception Processing Message c00000013 Parameters 75b6bf7c 4 75b6bf7c 75b6bf7c" This error started after attempting to use a recovery boot disk created with Acronis True Image 10 Home. I had to do a disk image restore in order to get rid of the error message. Why does the recovery disk not work? The entire application is pointless if the recovery disk doesn't boot.
