How to install win8 on a USB flash drive or mobile hard drive

Install Windows8 on a USB flash drive or a removable hard drive. Method: Windows 8 is installed on a USB flash drive or a removable hard drive. Of course, you need a USB flash drive or a removable hard drive (more than 5G). If you are using a USB flash drive, download Windows 7 USB/The DVD download tool software makes the Windows 8 DP ISO a bootable bootable disk. If it is a mobile hard disk, you need the following settings:

1. Computer & ndash; Right – Manage & ndash; Disk, ensure that there is a large enough space in the hard disk, or separate a 5-10GB space come out. 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 in it to this partition (including Hidden files) Or we can also prepare a DVD9 disc, burn (not recommended, not good to buy in the country, and not necessarily easy to buy) or we can also pass the network, local disk sharing, etc., through a boot disk Boot and then access Winload.exe I have not tested, not necessarily try.

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.)

You enter smoothly When selecting a partition, you need to press Shift + F10 to bring up the command line. OK, we need to create a VHD (Virtual Hard Disk) and mount the VHD.

Use the command line DIR to find a large enough partition on the existing partition, personally recommend to find a partition with more than 50GB of free space, remember his drive letter, such as D drive, enter DISKPART tool, command line input DISKPART.

Use the command create vdisk file=”d:win8.vhd” type=expandable maximum=50000 to create a VGB file with a maximum space of 50GB in D: (of course, you can also use a 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 and boot this VHD. System 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 report 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:

In the interface for selecting the installation partition, click refresh to find the partition you just mounted, confirm the size, select It, the next step is to officially install.

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.

After Windows8 is installed, he will generate his own Boot Manager, which supports direct booting of Win8 on the VHD, so you should see the following interface:

See the above interface and select 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. (Recommended familiar class operation, otherwise it is very easy to get into the system)

Well, roughly these few steps, the entire installation process is less than 20 minutes, and finally look at my screenshot after landing:
