How to install dual system, computer dual system installation steps

According to the network survey, I found that many users who bought a new computer are pre-installed Win7 operating system, but also need to use XP system. Therefore, you need to install XP in Win7.

Method 1 New installation with XP installation CD

First, you need to prepare a primary partition for installing XP system. It is recommended to use the disk manager to create a primary partition with a capacity of at least 10 GB in Win7 system (as shown in Figure 1). Then use the Win XP installation CD to start the computer and install it. The installation method is similar to installing XP system.

Need to pay attention to the problem:

1. Since Win7 has occupied two partitions by default (100MB hidden system reserved partition and system partition), for this reason, when selecting the installation location, Please select the partition according to the actual situation (as shown in Figure 2).

2. Since the partition was created in Win7, the XP installer does not recognize it, so you need to format it again in the next step.

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

Start the computer with the Win7 installation CD. When you are in the "Install Now" step, select "Repair Computer" until the "System Recovery Options" menu appears (as shown in Figure 3).

Select "Command Prompt", then enter the following commands in the pop-up Command Prompt window (enter each time you press Enter, if the message returns "Operation completed successfully" on the screen, continue to enter The next command, otherwise please check if the input is correct and re-enter):

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

bcdedit /set {ntldr} device partition =D:

bcdedit /set {ntldr} path ntldr

bcdedit /displayorder {ntldr} /addlast

Restart the computer after all commands are run, the boot menu will appear (Note: "D:" is the partition where XP is located, please modify it according to the actual situation).

Method 2 Installation with Ghost Image

I believe many users have the habit of making Ghost image CDs for backup and system installation. Relative to the use of XP installation CD to install, use XP Ghost image file to install, it is simpler. Just configure the boot menu after restoring the XP system.

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

After the completion, there is no startup menu, only to start under Win7. It does not matter, after entering Win7 as a system administrator, copy the three files "ntldr", "boot.ini" and "NTDETECT.COM" in the XP partition (all in the XP system root directory) to the Win7 partition. Then run the command prompt and enter the four commands above.

Summary: Installing XP in Win7 gives people the deepest feeling of "reverse behavior", and the installation is more difficult. Therefore, it is recommended that ordinary users install under the guidance of users with certain computer foundations. In addition, the text can not list all possible situations, but for some occasional some inexplicable errors (such as Win7 can not start, etc.), you can generally use the Win7 installation CD to repair.

Scenario 2 Traditional dual system solution - install Win7 under XP

I believe many users have the same loyalty to XP as the author, but the new features of Win7 are equally attractive, so Installing Win7 in XP naturally becomes a choice for many people. Relatively speaking, installing Win7 in XP is the easiest.

Method 1 Installing Win7 with CD on XP system

It is well known that the installation of the operating system from the low version to the high version is generally very smooth and will not cause any problems. Therefore, installing Win7 in XP system is also very smooth.

Questions to be aware of:

1. Please select "Custom Installation" instead of "Upgrade Installation" in the installation selection. XP cannot be upgraded to Win7 because they are different. Kernel.

2. When selecting the installation location, do not select the partition where XP is installed, otherwise you will not be able to create dual systems.

3. Installation to

The guide asks if you want to get important updates, please select "No" because the updates can be centralized after the installation is complete.

4. The partition space for installing Win7 must be at least 10GB and must be in NTFS format. Therefore, it is recommended to prepare the reserved installation space in advance in XP.

Method 2 Start the installation with the Win7 installation CD

It is easy to install Win7 in the XP system, but the fly in the ointment is that the partition cannot be adjusted. With the Win7 installation CD boot method installed, you can make any adjustments to the partition, including creating, deleting, formatting the partition and resizing the partition.

The problem you need to be aware of is similar to the previous method.

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

Scenario 3 Best Practices - Independent Dual System Installation

The above is a more traditional dual system installation because it relies mainly on the boot menu for booting, so it has higher limitations. Once the boot menu profile is corrupted, both systems will crash. The corresponding dual-system with no boot menu overcomes this drawback, and more importantly, independent multi-systems can also maintain each other.
