If setup does become non-responsive, you can do a cold boot, start the
machine again and boot Vista setup into safe mode to see if Vista will
finish setup.
Tip: (If setup becomes non-responsive or does not complete), do a Cold Boot
(reset the machine) > Start the computer, when the Windows Boot Manager is
displayed, select Windows Setup press F8 on your keyboard and setup should
continue.
What if setup still fails?
If you are upgrading/clean install, as noted, disable any external or USB
based devices you might have attached to the computer. Also, disable any
Security software before launching setup and ensure that you meet the
minimum system requirements for Windows Vista.
Turn Off Serial Key Devices: Windows Vista does not support Serial Key
devices. If you are upgrading and you currently use Serial Keys with an
alternative input device, you must turn off Serial Keys and install another
input option before the upgrade. To turn off Serial Keys in Windows XP, open
Accessibility Options in Control Panel. For more information, go to the
Microsoft Accessibility website (
http://www.microsoft.com/enable).
