My own solution: Since the computer went into infinate booting loop, I changed the boot drive and booted from the disk. Upon starting the boot from the CD, I was able to format my c drive and in less that 2 hours, I am loaded and on-line. This is for a clean install from Vista 64 bit to Windows 7 Ultimate 64 bit. After a week of fighting with this install and finding out I had to perform a clean install (no real upgrade), this was so simple I'm kicking myself. I hope this helps someone get their operating system up quicker. I followed the instructions in detail including running the migration software for hardware/software issues. That came back ok; saved my personal data to an external HD then proceeded to do the clean install. The install is stalled at "Completing Install" with the dots moving. The status bar is about 80% complete and I can move the cursor. It has been in this state without movement for 13 and a half hours. My system is: Asus M2N-SLI Delx AMD x2 5400 4 gig of Crucial Ballistic memory EVGA nVidia 9800 GT 512 ddr3 Maxtor 500 gig hard drive for the c drive All peripherals are disconnected other than the monitor. Returned home from work after running an additional 4 hours and my computer was off. Started back up and now just restarts after a message states restarting will restart the setup but just loops. I have been down a week and have not been able to access my important files just because Microsoft cannot get their act together on something that should be automatic these days. My Vista Business 64 bit ran great without any issues. I am doubting the $200.00 spent on an operating system that you cannot install. Help someone!
