Mode of continuous reboot after an unsuccessful attempt, how can I return to a functional version of windows (Vista or 7)?

I tried to upgrade to Windows 7 Vista SP1 from a disk of retail bought at Costco.  I received an unsuccessful installation and everything seems to be ok with a rolling Vista.  I woke up this morning to my system stuck in reboot mode.  I can't even Windows Safe Mode to work.  What can I do to get back to Vista?  I promise you that I'll never try to update again... Please help.

Hi HelpPleaseWindows7,
 
Thanks for visiting the site of Microsoft Windows Vista Community!
 
(1) remove any external devices like floppies, CD, flash, printers and computer DVD drives and restart.
(2) If this helps not to start your computer, use the Vista installation cd
(3) try to get the error message by disabling "auto restart in case of system failure"

If you have a Windows Vista installation disc:
Insert the installation disc.
Restart your computer.
Click the Start button, click the arrow next to the button lock and then click on restart.
If you are prompted, press any key to start Windows from the installation disc.
Note
If your computer is not configured to start from a CD or a DVD, see the documentation provided with your computer. You may need to change your computer's BIOS settings. For more information, see BIOS: frequently asked questions.

If the Startup Repair tool is an option of recovering preinstalled on your computer:

Do one of the following:
If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.
If your computer has more than one operating system, use the arrow keys to select the operating system you want to repair, and then press and hold F8.
In the Advanced Boot Options screen, use the arrow keys to highlight repair your computer and press ENTER. (If repair your computer is not listed as an option, then your computer does not include startup as a preinstalled recovery option repair).
Select a keyboard layout, and then click Next.
Select a user name and password, and then click OK.
