You dont have to go thru all that to repair the Vista bootloader. It rather simple. If you have EasyBCD isntalled or the Vista DVD. If not you can download the Vista repair CD from here and use that as well. All the instructions are on this wiki page:

Your instructions are way to complicated. It is much simpler than that. Why would you need to reset the CMOS and BIOS in that effect to get the Vista bootloader back? That is going way to far out of line to do something so simple.
