Pandlouk, I am extremely grateful to you for your hard work in devising and articulating the procedures above so that even I could follow them. I now have FD-ISR successfully installed on my Windows 7 64-bit PC and it is such a relief. None of the backup imaging programs I've tried (True Image, Paragon, Macrium Reflect) have been 100% reliable on my newest PC. Thanks to you and my beloved FD-ISR, I can compute with confidence again. The Bootsec_x64 file confounded me at first since I'd never dealt with a file which had double extensions. Once I researched how to reveal the second "hidden" extension so I could delete "txt", it was a snap to install FD-ISR. My only problem now is I haven't been able to delete the 101 MB of unallocated space which formerly held the Win 7 System Reserved. I made a backup image as you advised (using True Image Home 2010) but didn't see any obvious way to remove the 101 MB when I restored the image. I installed Partition Wizard and used it to expand the size of my C partition until it filled the unallocated 101 MB. After rebooting, however, the program gave an error message saying there had been some registry-related problem then check disk ran. After my PC restarted, Disk Management confirmed the 101 MB space had been incorporated into the C partition but, inexplicably, my D partition (which contains the HP system recovery files) was now untitled and listed as a "generic volume." I restored my PC using a backup image made just prior to installing Partition Wizard. I hope there's no problem with having this 101 MB unallocated space remaining on my primary hard drive. Finally, I wish there was some method where folks with a valid FD-ISR license who follow pandlouk's procedures and install FD-ISR on a Windows 7 PC could purchase a second license key from Leapfrog so they wouldn't have to uninstall FD-ISR from another PC in order to be in compliance with the licensing agreement.
