There seems to be a lot of discussion in this forum about how FDISR works and what happens when FDISR is used with imaging software. One question that comes up from time to time is, "Should I disable the pre-boot screen when taking an image?" (General consensus is YES, it cannot hurt). I decided, under the advice of my good friend Peter2150 to run a test. The test went as follows: TEST 1 Fresh installation of Windows XP Pro, not from image, but rather the old fashioned hard way. Update and patch windows. Install FDISR (most updated version), but do not create secondary snapshot. Use Image for DOS to create and verify image onto external drive via USB 2.0 [pre-boot was enabled during the creation of the image]. Restored the image from Image for DOS. During the initial reboot after restoration, the pre-boot screen was present. Rebooted one more time to ensure that the pre-boot screen remained and it did. Created a secondary snapshot using FDISR. Booted to secondary snapshot to verify that it functioned normally and it did. Booted back into the primary snapshot. TEST 2 Disabled the Pre-boot Uninstalled FDISR and all of its components Restored the original image using FDISR (which had FDISR installed with pre-boot enabled). Upon initial reboot after restoration, the pre-boot screen was NOT present. I was able to simply enable pre-boot while in Windows and reboot. I will let the experts haggle over what the results of my test mean, but what it means to me is that Image for DOS does not mess with the MBR.
