If you're Troubleshooting Windows 7 Failure to Boot
I had the same issue with my wifes Toshiba Satellite C55-A5100 and looked everywhere I could to no avail. After playing with the bios settings I found that I had to change the security to disabled, the UEFI to CMS, left the hard disk on ACHP, and had do disable the USB 3.0 in the bios and then I was able to install Windows 7 Ultimate x64.
I had same problem after Win XP-Vista to Win 7 - 32bit upgrade, problem were drivers - old drivers which were in system from old installation, i have to get rid of them through Sysiternals Autorun-Drivers and after that restart whole Windows 7 upgrade.
Its dangerous thing Vista could easily stop boot when some driver is removed, so i recommed to often create whole partition image or migrate machine to virtual machine - remove drivers and install upgrade and move image back to physical machine.
