Win8 dual system installation diagram tutorial (2)

U disk installation Win8 system method
When the BIOS is set to boot the U disk boot, or do not need to set BiOS, boot into the boot item and select the boot device is also available (generally enter the boot screen press F10, some brands The notebook will be different). If you only want to install a Windows 8 single system on your own computer, you don't need to install a dual system that coexists with Windows 7. From now on, you only need to follow the instructions to install it, and you can complete the installation in less than 20 minutes. If you are installing a dual system, continue to refer to the virtual hard disk partition setting method on the next page.
Note:
If your notebook can not enter the boot item selection menu, then you need to simply set up your notebook's BIOS, the method is very simple, press F2 to enter the BiOS settings after booting, select the Boot option, in In the Hard Disk Drives, adjust the order of the startup items and put the U disk in the first place.

1. when you enter the screen prompts to install Windows 8, press Shift + F10 on the keyboard, it will jump out the window command-line mode on the screen.
2. Since we started the boot with a USB flash drive, the order and number of the hard disks of the system are likely to be different from the order you saw before in Windows 7. Therefore, we recommend using "dir" command to check the remaining space of each hard drive, at least to find a free space on hard disk 20GB or more to make a virtual hard disk partition when

enter dir command lookup hard disk space
3. Next enter the "diskpart" command, which is the command used to make the virtual hard disk settings.

enter diskpart to set the virtual hard disk
now, you should see the prompt command in front of a column written diskpart, that you have entered the diskpart command mode. At this time, enter the following command: "create vdisk file=d:\\win8.vhd type=expandable maximum=30000" This means that a virtual hard disk partition called Win8.vhd is created in the D drive, and the category is expandable. The size of the hard disk is 30GB.

continue to set the virtual hard disk partition command
4. If the build is successful, the window will display a successful information established. At this time, continue to enter the following command: "select vdisk file=D:\\win8.vhd" This means that "D:\\Win8.vhd" is selected as the virtual hard disk partition. Finally, type "attach vdisk" to indicate that the created virtual hard disk partition is mounted, and you are done.
As long as the above steps show successful information, this means that you have finished making the virtual hard disk. Finally, you can leave the "EXIT" command or close the window directly.
5. Install the Win8 operating system in the order indicated. When installing Windows 8, you can see that the virtual hard disk partition we just added has appeared in the list of installed partitions. If you can't check it, you need to re-set the above settings and make sure that each step prompts the operation.

installation process, we can see the new virtual hard disk partition
6. When you specify the system is installed after the virtual hard disk partition we just created, you can start the installation of Windows 8. The entire installation process is quite fast and can be completed in about 20 minutes. Moreover, when Windows 8 is installed, because it has already detected the Windows 7 system before the computer is detected, it will automatically help you establish Boot Manager and establish a boot option. And this option is also the display interface of Metro Style, which is quite different from the format of the previously rigid command line.

Summary and precautions

should be noted that, earlier when we create a virtual hard disk partition, although the establishment of the type Set to expandable, you can dynamically amplify the hard disk capacity, but the maximum space we set can not be greater than the available space available on the physical hard disk. If the capacity of the available space is exceeded, although there will be no problem at the time of setting, if the system is installed in half and the space is not enough, there will be a message indicating that the installation error is displayed, and it is even more troublesome. This is what we must The reason for the first step of testing.

if space is not allocated in the installation process will complain
