To install Windows 8 in a USB flash drive or a removable hard drive, you need a USB flash drive or a removable hard drive with a memory larger than 5G. If you use a USB flash drive, you only need to download the Windows 7 USB/DVD download tool software and make the Windows 8 dp iso a bootable boot disk. But if you use a mobile disk, you need to follow the tutorial below.
1. Computer – Right – Manage – Disk, ensure that there is a large enough space in the hard disk, or separate a 5-10GB space. Then in Windows System Management, set this partition to active state in Disk Management:
2. Then read the ISO with a virtual CD-ROM drive and copy all the files inside to this partition (including hidden files). Or we can also prepare a DVD9 disk, burn (not recommended, domestic is not good to buy, and buy is not necessarily easy to use) or we can also through the network, local disk sharing, etc., through a boot disk boot and then access Running Winload.exe I haven't tested it, not necessarily a good one.
3. Start the installation: First check if your computer motherboard supports USB device booting. If it is, you can choose to boot through USB when booting, you can successfully enter the Windows 8 DP installation interface.
(Note: If you can't enter normally, for example, he reports HAL errors, etc., then you can only congratulate, your hardware is too avant-garde, it does not support.)
When you successfully enter the selection partition, you You need to press Shift + F10 to bring up the command line. OK, we need to create VHD (Virtual Hard Disk) and mount VHD.
Use the command line DIR to find a large enough partition on the existing partition. Personally, I suggest to find a partition with more than 50GB of free space. Remember the drive letter, such as the D drive, and enter the DISKPART tool. Enter DISKPART from the command line.
Use the command create vdisk file=”d:win8.vhd” type=expandable maximum=50000 to create a VGB file with a maximum space of 50GB dynamically created under D: (of course, you can also use fixed size type=fixed) .
You must be reminded that you should not think that he is dynamically adding space, I can create it in a partition with less than 50GB left. If so, although the general virtual machine can read the system in the VHD or File, but booting directly through the physical machine or not, because the boot starts when she wants to create a logical partition according to the VHD settings, so if you are less than 50GB, and he still takes 50GB of space, it will Reporting an error with insufficient space. So be sure to remember to choose a partition with enough space and then set a reasonable maximum.
Then select this VHD file and mount it:
Click refresh under the interface to select the installation partition, find the partition you just mounted, confirm the size, select it, the next step is to officially installation.
The above steps to create a VHD can also be done in your existing Win7 disk management, menus, actions, create VHD:
Then, restart and install successfully.
When Windows8 is installed, he will generate his own Boot Manager, which supports direct booting of Win8 on VHD, so you should see the following interface:
See the above interface. Choose the system you want to enter.
If you are familiar with BCDEdit, you can also modify the Boot Manager content yourself or use the Windows 7 Boot Manager. The EasyBCD tool is recommended here. It has a simple visual interface and is much more intuitive than the bcdedit command line. (It is recommended that the familiar classmates operate, otherwise it is very easy to get into the system)
It took about 20 minutes and it was finally completed. The steps are probably just a few steps. Finally, share the screenshot after I finished.
