I installed the blood and tear history of win8 and win7 dual system

        Some time ago, the disciple installed the system, because the notebook originally brought win8, he did not want to replace the original system. I decided to install a dual system. So according to the previous routine, but there is a problem. First, the first problem encountered is: how to enter the BIOS, set to U disk boot. Win XP, Win 7 and other systems will have certain buttons to enter the BIOS settings, such as holding down the F2, F12, ESC, DELETE keys, etc., but these methods are not applicable to Win8 systems — — because Win8 default The boot mode does not have these options at all. After reviewing the information, it turned out that Microsoft has added 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. So how do I get the Win8 system into the BIOS setup? From the Win8 system & ldquo; computer settings & mdash; advanced startup & rdquo; restart into the BIOS settings interface Win8 desktop open, finger swipe from the right side of the screen to the middle or press the "Win + I" shortcut to open the Win8 super button ( Charm column), click “change computer settings”. 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. Www.dnzg.cn Second, the children's shoes set up the BIOS generally the next step? Do you want to change the system? Indeed. The purpose of entering the BIOS is to use the U disk to install the Win 7 system. After entering the BIOS, the problem came again: unable to directly enter the U disk system automatic installation interface. Looking for a long time, found that in the BOOT settings, there is a Legacy and UEFI options, you can only choose the traditional legacy to recognize the U disk automatic installation system. So after the setup is completed, the PE is successfully entered. I thought this was over, but there were unexpected events, and the imaginary things often showed unexpected situations: the system showed that the installation was completed and restarted. But after restarting, I still can't get into the win8 interface and can't get the boot interface of win7. There is also no win7 boot option in the system boot. What to do about this? It turns out that you need to fix the boot. After downloading a NTBootAutofix fix, the miracle happened. After successfully entering the win7 system, and then follow the prompts to set up, it was only then that you were relieved.
