Enjoy WIN7/XP dual systems in one partition

In general, the conventional way to install a dual system is to install different systems in different partitions, so that not only to plan the partition in advance, but also the backup and maintenance of the dual system is very troublesome. Today to introduce a new method, you can change the system into a single file, and can be placed in any partition, you can move any, backup and restore as long as the copy and paste can be.

Step-by-Step Single file system production process

At present, Windows7 and Windows XP (hereinafter referred to as Win7 and XP) are the two most commonly used systems, and many users choose to install a dual system. Win7 native support is started as a virtual disk (VHD), Windows XP is driven by "Firadisk", or it can be started in a mirrored manner.

Therefore, based on the above characteristics, for the installation of "WIN7+XP" dual-system users, we can actually do not install the entity system, and as long as the separate production of a VHD file and mirror files can be perfect to enjoy the dual system. In order to let everybody to the operation process clearer, we subdivide the operation steps into the following 5 steps, everybody just presses this process to produce can.

1, create a VHD disk on the basis of existing XP or Win7 system;

2, load the VHD disk and install the Win7 system on the disk, and then obtain the Win7 single file system;

XP single file system in accordance with the "put the system into memory to build their own high-speed Ramos" in the article introduced the method to obtain;

3. Copy the necessary startup files to D disk and format C in WinPE, and change the boot record to NT60 format;

4. Copy the startup file and the single file system to the C disk;

5, in the WinPE run "Bcdtool.exe", and then configure the Win7 and XP single file system startup.

The first step is to get the Win7 single file system

Because the XP system does not support creating and loading the VHD, the XP user first prepares a WinPE system and then creates and loads the VHD to install it. The method is simple, just copy all the files in the Win7 CD to D disk, then copy the downloaded "Geldr" file to C, and then open "C:boot.ini" to add the boot. When you are done, reboot the system into WinPE, then start the command prompt and enter the command "Diskpart/sd:diskpart.txt" to create and load the VHD.

Note: Win7 users go directly to the system, start the command prompt program as an administrator and execute the above command.

Next, continue to enter the "D:sourcessetup.exe" Activation installation in the Command Prompt window (assuming that all the Win7 files have been copied to D disk), and install the system to the virtual hard disk created above when you want to install the system to which partition step, this virtual hard drive is labeled " Disk1partion1 ".

The remaining actions follow the on-screen prompts to complete the Win7 installation, thus obtaining the Win7 Single file system installed in "D:WIN7.VHD".

Tip: Only the "diskpart" command for winpe3.0 (that is, Win7 's own WinPE) supports the creation of VHD files, so be sure to use Win7 core WinPE. The "Diskpart.txt" in this article is a batch file that has already been made, by default in D disk (the D disk must be NTFS formatted and guaranteed to have enough space to create system files) to create a 10gb "win7.vhd" file. You can use "notepad" to open "diskpart.txt" according to their own circumstances to modify.

After you get the Win7 single file system, you now have two choices:

1, if you are now installed XP system, and your memory is not very large, then you can choose to retain the existing XP system, and then only need to configure the Win7 WinPE in the boot of a single file system can be composed of "traditional XP system +win7 Single file system" dual system;

2. If you are installing an XP or Win7 system now, and your memory is relatively large, then you can choose according to the "put the system into memory to build their own high-speed Ramos" in the article, to create a running in the memory of the XP system, and then format the current system, and then configure the boot in the WinPE , we get the dual system of "Win7 Single file system +xp Single file System".

Of course, for the sake of insurance, it is recommended to reserve the original system, reformat the original system and reconfigure the boot after confirming that there are no problems with the single file system. Of course, the original system can be retained, but the final result is to generate three systems: the original system +xp single file system +win7 Single file system.

How to choose the specific, it depends on their own request.

　The second step is to configure a single file system boot

To choose to make "Win7 Single file system +xp Single file system" for example, first put the production of "winxp.img" in the D disk, and then start the WinPE system (you can use the Win7 CD-ROM directly), in the presence of the choice to install the language interface, press "SHIFT+F10" Start a command prompt, and then enter a command based on the description of the "Configure a single File system startup command" document provided in the package, press the prompt to format the C disk, and then copy the necessary files to the C disk.

After you have done this, use "Bcdtool" to configure the Win7 and XP single file system startup.

The boot configuration of the Win7 single file system is also done in the command prompt environment. Enter "D:bcdtool" to start the "Bcdtool" program, and then click "Start configuration → open", select Open "C:BOOTBCD" and configure the Win7 VHD boot, as follows:

Click the edit → New Vista startup Project button on the Bcdtool menu bar, select the "Device" of the right pane after the new item is selected, and change it to "partition=p:" (that is, the letter that loads the WIN7.VHD virtual disk if you enter a download to the Configure the commands in the single file system startup command document, the VHD is automatically loaded after the P disk, otherwise please modify according to the actual situation, "description" (boot menu display name) changed to "Windows7vhd", "osdevice" changed to "Partition =p: ".

Once completed, we will then configure the XP single file system startup.

Continue clicking "edit → new Real mode startup item" To change "description" to "BOOTXP" and other settings with default values. Note that at this point must ensure that C disk has "GRLDR.MBR", "Menu.lst", "Geldr" these several files, or you can not complete the XP single file system startup.

Hint: In fact, whether it's XP or Win7, we just have "bootmgr" and "BCD" profiles, and "Bcdtool" makes it easy to configure their startup without having to worry about which partition these systems are installed on.

Now reboot the system, we can select "Windows7vhd" in the Multiple boot menu into the Win7 Single file system, select "Bootxp" Into XP!
