Turn on Vista startup options by pressing the space bar

        Compared to Windows XP, Vista has slightly different startup options. In XP, the user must start the option by pressing F8. In Vista, this method is still valid, but at the same time, the user can also achieve the same effect by pressing the space bar. In addition, as the successor to Vista, Windows 7 will inherit this tradition. After BiOS is loaded, press the space bar to call out the Windows Boot Manager.
"In addition to pressing F8 in Windows Vista or Windows Server 2008, there are some other methods that can be used to open the boot options. The next time you reboot, you can try the Windows startup screen after BiOS is loaded. Press the space bar. If you just press the space bar at that time, the Windows boot manager will appear. At this point, the user can choose the OS at will, or press F8 to open the restore menu, etc."
Of course In Windows 7, when the user presses F8, the system restore menu will appear. At the same time, there will be an F10 button for the user to open the startup parameter editor. However, the parameter manager is only temporary, and more options rely on msconfig.
"This method can also be used on the installation CD of Vista or Server 2008. Just when the system prompts "Press any key to boot from CD/DVD", tap 2, 3 under the space bar, at this time, Windows starts The manager will appear again, and the Windows installation options will also appear in the list."
