Disable automatic restart on system failure
Unlike the previous eight entries here, this option merely changes a setting
so you can determine why Windows won??™t start. By default, if Vista
crashes while it??™s loading (see ???Blue Screen of Death,??? later in this chapter),
it reboots your PC so fast, you can??™t read the error message on that
infamous blue screen. Choose Disable automatic restart on system failure
if you want to read the message and then reboot by hand.
Disable Driver Signature Enforcement
By default, the 64-bit edition of Windows Vista won??™t allow you to
install any device drivers that haven??™t been digitally signed (a bureaucratic
requirement to get the Microsoft certification logo on a product??™s
packaging). In theory, you should be able to choose Disable Driver Signature
Enforcement to allow your PC to install nonsigned drivers, but
in practice, this never works. Instead, boot Windows normally, open a
Command Prompt window (in administrator mode; see Chapter 8), and
type the following:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
and then press Enter. Close the Command Prompt and restart Windows
for the change to take effect. If that doesn??™t help, you may have to
forgo supporting a specific device until the manufacturer makes a
signed, native (64-bit) driver available.

Troubleshooting
Repair your computer (not shown in Figure 6-4)
You may see this option if your PC came with Vista preinstalled and
your PC manufacturer was too cheap to include a real Windows installation
disc.
