U disk installation Windows8 achieves peaceful coexistence with Win7

        Some friends want to play Windows8? Now that Win8 DP is out, here is a great way to install Windows 8 on a USB flash drive or a removable hard drive, and how Win8 and Win7 can coexist peacefully.

Prepare the installation file: Prepare a mobile hard disk or U disk larger than 5GB (if you install a version without development tools, 4GB is enough), if it is a U disk, download the Windows 7 USB/DVD download tool Work to make the Windows 8 DP ISO a bootable bootable disk. If the mobile hard drive, need to be set as follows:

(I choose this program) to ensure that there is a hard disk partition has enough space, or independent sub-space of a 5-10GB out. Then in Windows System Management, set this partition to active state in Disk Management:


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, not good to buy in the country, and not necessarily easy to buy) or we can also boot through a network boot disk, local disk sharing, etc. Access to run Winload.exe I have not tested, not necessarily a good try.

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, he 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.

DIR command line, etc. to find a large enough partition on an existing partition, there are more than personal recommendations to find a free space of 50GB partition, remember his 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 under 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 the VHD file and mount him:



click on the next refresh refreshed choose to install the partition interface, you just find a mounted partition, confirm the size of the After that, select it and start the official installation.

above steps can also be done to create a VHD in Win7 you have in disk management inside, menus, action, create VHD:


Then, restart the installation was successful.

After Windows 8 is installed, he will generate his own Boot Manager, which supports direct booting of Win8 on VHD, so you should see the following interface:

< BR>
See the above interface, 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 students familiar with the operation, otherwise easily made into the system)

Well, simply that roughly a few steps, the entire installation process is probably less than 20 minutes, and finally look after landing my shots:

attached: and I had Office 2010 now seems very stable on Win 8 DP, Windows do the same strain of fairly authentic . But it really shows that Win 8 is just the same as Win 7 and adds something. Mainly concerned about the development of his Metro Style.
