Windows 7 and XP dual system installation Method rollup

With the release of the official version of Windows 7 (Win7), many friends are very concerned about installing Win7 and XP dual systems, especially for the dual-system problem of installing XP under Win7. This article will introduce three kinds of Win7 and XP dual-system installation program, I believe there must be a suitable one for you. Our goal is: let WIN7+XP harmonious coexistence!

Traditional dual-System solution--win7 install XP

It is believed that many of the users who bought the new computer are pre-installed Win7 operating system, but for some reasons, they also need to use the XP system. So you need to install XP in Win7. Compared to the installation of Win7 in XP, it is much harder to install XP in Win7.

method to install a new installation CD with XP

First, you need to prepare a primary partition to install the XP system. It is recommended that you use Disk Manager to create a primary partition with a capacity of not less than 10GB in the Win7 system (as shown in Figure 1). Then use the Win XP installation CD to start the computer and install it, similar to the installation of the XP system.

The issues to be noted:

1. Since the Win7 has been used by default for two partitions (100MB of hidden system-reserved partitions and system partitions), for this reason, select the partition (as shown in Figure 2) as appropriate when choosing the installation location.

2. Because the partition was created in Win7, the XP installer is not recognized, so you will need to format it again in the next step.

After the installation is complete, you will only be able to enter the XP system, which requires further manual configuration to restore the boot menu.

Start your computer with the Win7 installation disc, and when you go to the "Install Now" step, select Repair computer until the System Recovery Options menu appears (as shown in Figure 3).

Select command prompt, and then enter the following command in the command Prompt window that pops up (click enter for each entry, and if you return the "Operation completed successfully" message on the screen, continue to enter the next command, or check if the input is incorrect and re-enter):

bcdedit/create {ntldr}-D "Windows XP"

Bcdedit/set {ntldr} device Partition=d:

Bcdedit/set {ntldr} path NTLDR

Bcdedit/displayorder {ntldr}/addlast

When all commands are run and restart the computer, the boot menu appears (note: where "D:" is the partition for XP, please modify it according to the actual situation).

Method two uses ghost mirror to install

I believe many users have the habit of making ghost mirror discs for backup and system installation. Compared with the installation of XP installation CD-ROM, the use of XP ghost mirror files to install, it will be easier. You only need to configure the Startup menu after you restore the XP system.

As with the above method, first prepare a primary partition to restore XP under Win7. Then use the appropriate tool CD to start the computer and restore the XP ghost image file to the primary partition that you just prepared.

When finished, there is no boot menu for the moment and can only be started under Win7. Never mind, after entering Win7 as a system administrator, copy the "NTLDR", "Boot.ini", "Ntdetect.com" three files (all under the XP system root) in the XP partition to the Win7 partition. Then run the command prompt and enter the 4 commands above.

Summary: Install XP in Win7, give people the deepest feeling is "perverse", the difficulty of installation is also relatively high, so it is recommended that ordinary users should be installed under the guidance of a certain computer based user. In addition, the article can not list all possible occurrences, but for occasional some inexplicable errors (such as Win7 can not start, etc.), the general use of the Win7 installation CD to repair.

Please click on the "Next page", we introduce the traditional dual-system solution--xp install Win7.

Traditional dual-system scheme--XP installation Win7

I believe that many users of the loyalty of XP is the same as the author, but Win7 new features are also attractive, so, in the XP installation Win7, naturally become a lot of people's choice. In contrast, installing Win7 in XP is the easiest.

Method an XP system with CD-ROM installation Win7

As we all know, the operating system from the low version to the high version of the installation, is generally very smooth, there will be no problem. Therefore, the installation of Win7 in the XP system is also very smooth.

The issues to be noted:

1. In the installation selection of the face please note that choose "Custom Install" instead of "Upgrade Installation", XP does not upgrade to Win7, because they are different cores.

2. When choosing an installation location, do not select a partition that has XP installed, or you will not be able to create a dual system.

3. The Setup wizard asks if you want to obtain an important update, select "No" because the update can be centralized after the installation is complete.

4. The partition space for installing Win7 must not be less than 10GB and should be in NTFS format, so it is recommended that you prepare for the reserved installation space in advance of XP.

Method two uses the Win7 installs the CD-ROM to start installs

The installation of Win7 in XP system is simple and easy, but the drawback is that the partition can not be adjusted. The installation of the WIN7 installation CD-ROM method allows you to make arbitrary adjustments to the partitions, including creating, deleting, formatting, and resizing partitions.

The problem that needs to be noted is similar to the previous approach.

Summary: Two methods, the user can choose according to individual circumstances, the basic operation is very simple, as long as the corresponding prompts can be completed. The Startup menu can also be generated automatically.

Please click on the "Next page", we introduce the best solution-independent dual system installation.

Best solution-Independent Dual system installation

Described above is a more traditional dual-system installation scheme, because it relies mainly on the boot menu to boot, so the limitations are high, once the boot menu profile damage, both systems will be paralyzed. and the corresponding without the boot menu of the independent dual-system is overcome this disadvantage, more importantly, independent multiple systems can also be mutually maintained.

Because there is no boot menu, to choose to enter a different system, you can use the Windows section Magician extracted from the system conversion tool.

First, use third-party tools (such as partition Magician) to create two primary partitions on your hard disk (for installing XP and Win7, respectively) and one of them to be activated. When a primary partition is activated, another primary partition is automatically hidden, which is exactly what we need. In this case, we first activate the partition that installs Win7.

Tip: Once the win7,dos version of the partition is installed in the system the magician will not recognize the hard drive properly, for this reason, please create two primary partitions in advance.

Then, start the computer with the Win7 installation CD and install the Win7 into the scheduled partition. After the installation is complete, start the system and run "Pqbw.exe" in the Conversion tool, select "Restart Now" in the pop-up dialog box (shown in Figure 4) and click "OK" to restart the computer. At this point, the partition used to install XP will be active, and the partition that installs the Win7 will be automatically hidden. Next, use the XP installation CD to boot your computer to install XP, and then automatically start XP when you are done.

Tip: In this step, you can also use the Ghost mirrored file to install XP.

At this point, no matter which system you boot to, just run "Pqbw.exe", select the partition where the other system is located and reboot to switch to another system. At the same time, the tool software can be used to back up or restore another system, regardless of the system. If it is really unlucky to get home, both sets of systems can not start, but also through WinPE and other tools such as CD-ROM to repair.

The simplest and easiest way to do this is to install Win7 under XP, which is not too difficult for ordinary users to operate. Win7 installation of XP, it is relatively difficult, and easy to create a lot of problems, so do not recommend the ordinary user installation independently, the installation of independent multiple systems, the difficulty is relatively moderate, but the advantages are quite obvious, more suitable for computer technology enthusiasts try to use.

Therefore, for those who have installed Win7, you can consider doing a Win7 system backup after reformatting the system, installing XP and then using Backup files to restore the installation of Win7, relatively simpler and safer to operate.
