|Software problems on the hard drive CANNOT cause no video while booting the computer BEFORE Vista is supposed to load. |
If you're getting no video at all, your computer has a hardware problem.
If you ARE seeing video while booting the computer BEFORE Vista is suppsed to load....
What are the system recovery options in Windows Vista?
"The System Recovery Options menu is on the Windows installation disc. The menu might also be installed on your hard disk if your computer has preinstalled recovery options."
NOTE that brand name system original software installations often DO have preinstalled recovery options.
In that case you DON"T NEED a Windows Vista DVD to try those options.
