Win8 system set U disk boot method

Most of the computers now support U disk booting, which can play a big role in system crashes and quick system installation. Let's take a look at the Win8 system to set up the U disk boot method.
Win XP, Win 7 and other systems start, there will be a certain button to enter the BIOS settings, such as press and hold F2, F12, ESC, DELETE button, etc., but these methods are not applicable to Win8 system — — because Win8's default startup mode does not have these options at all. In fact, this is Microsoft's addition of a new technology HYBRID BOOT (mixed start) technology in Win8. In this way, it is equivalent to the advanced sleep mode. It is a hot boot when booting normally, so you can't enter the BIOS no matter what you press F2, DEL or whatever.
1, from the Win8 system "computer settings & mdash; advanced startup" in the reboot into the BIOS settings interface
Win8 desktop open, the finger swipe from the right side of the screen to the middle or press "ld+;" The shortcut key opens the Win8 super button (Charm column), click “change computer settings & rdquo;. Then go to & ldquo; computer settings & rdquo; & mdash; & mdash; & ldquo; regular & rdquo; & mdash; & mdash; at the bottom has an advanced startup function, activate the immediate restart button, restart, see & ldquo; select an option & rdquo; interface, select & ldquo ;Troubleshooting”, then see three options, click on the bottom of the "advanced option", then you can see "UEFI firmware settings" (this is a BIOS specification introduced by Intel), and finally You can start the reboot. After a normal restart, the system will automatically enter the BIOS setup interface.
2, enter the BIOS setup interface by modifying the power option. Since it is a ghost of HYBRID BOOT technology, then we can turn it off. Click the left (or right) button on the bottom right corner of the desktop. Enter the power option, click “ need to password when waking up, there is a setting at the bottom of the page. In this case, you can't change it directly. You need to click ““Change the currently unavailable settings” to change it.
3, enter through forced shutdown. Forcibly shutting down is to press and hold the power button for 5 seconds or more to force the computer to turn off and then on. By the way, this method, I tried on a computer, seems to work.
After entering the BIOS, there is a Legacy and UEFI option in the BOOT settings. Only the traditional legacy can be selected to recognize the U disk automatic installation system.
