Windows 7 and WindowsXP dual system installation method summary

  
With the release of the official version of Windows 7 (hereafter referred to as Win7), many of my friends are very concerned about how to install Win7 and XP dual systems, especially for the dual system problem of installing XP under Win7. This article will introduce three Win7 and XP dual system installation solutions for everyone, I believe there must be one that suits you. Our goal is: Let Win7+XP coexist harmoniously!
Traditional dual system solution ——Install XP under Win7
I believe that many users who bought a new computer are pre-installed Win7 operating system, but because of some The reason is that you need to use the XP system. Therefore, you need to install XP in Win7. Compared with XP, Win7 is installed, and it is more difficult 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.




1. Since Win7 has occupied two partitions by default (100MB hidden system reserved partition and system partition), please select the installation location according to the actual situation. The situation selects the partition (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 go to the “Install Now” step, select “Repair your 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 enter a carriage return, if the screen returns “ the operation completed successfully & rdquo; information , 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
After all commands are run, restart the computer and the boot menu will appear (Note: where “D:” For 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 completion, there is no startup menu, only boot to Win7. It doesn't matter, after entering Win7 as a system administrator, copy the three files (all in the root directory of XP) of Win7 to the XP partitions, "ldld;", "ld.ini", "“boot.ini", and "NTDETECT.COM". In the partition. Then run the command prompt and enter the four commands above.
Summary: Install XP in Win7, giving people the deepest feeling is "reverse action", the installation is more difficult, so it is recommended that ordinary users install under the guidance of a certain computer-based user. 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.
Please click “next page", we introduce the traditional dual system solution —— XP install Win7.
Traditional dual system solution ——XP installed under Win7
I believe that many users have the same loyalty to XP as the author, but the new features of Win7 are also attractive, so install Win7 in XP. Naturally, it has become the choice of many people. Relatively speaking, installing Win7 in XP is the easiest.
Method 1 XP system to install Win7 with CD-ROM
It is well known that the operating system from the low version to the high version of the installation, generally very smooth, there will be no problem. Therefore, installing Win7 in XP system is also very smooth.
Need to pay attention to the problem:
1. Please select "“custom installation" in the installation selection. Instead of "upgrade installation", XP cannot be upgraded to Win7 because they are different kernels. .
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. The installation wizard will ask 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 Win7 installation CD
It is easy to install Win7 in 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 pay attention to 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.
Please click “next page", we introduce the best solution —— independent dual system installation.
Best solution —— stand-alone dual system installation
The above is a more traditional dual system installation solution, because it mainly relies on the boot menu to boot, so the limitations are higher, once the menu configuration file is started Damaged, both systems will be paralyzed. The corresponding dual-system with no boot menu overcomes this drawback, and more importantly, independent multi-systems can also maintain each other.
Because there is no boot menu, to choose to enter a different system, you can use the system conversion tool extracted from the Windows version of the partition magic.
First, use a third-party tool (such as "Partition Magic" to create two primary partitions on the hard disk (for XP and Win7 respectively) and set one of them to be active. When a primary partition is activated, the other primary partition is automatically hidden, which is exactly what we need. In this example, we first activate the partition where Win7 is installed.
Tip: Once Win7 is installed in the system, the DOS version of the partition magic will not be able to identify the hard disk. For this, please create two primary partitions in advance.
Then, start the computer with the Win7 installation CD and install Win7 into the predetermined partition. After the installation is complete, start the system and run “pqbw.exe” in the conversion tool. In the pop-up dialog box (shown in Figure 4), select the XP partition and then select “Restart Now”, click “OK&rdquo ; Restart your computer. At this point, the partition used to install XP will be active, and the partition where Win7 is installed will be automatically hidden. Next, use the XP installation CD to boot the computer to install XP, and will automatically start XP when it is finished.

Tip: In this step, you can also use the Ghost image file to install XP.
At this point, no matter which system is booted, just run “pqbw.exe”, select the partition where another system is located and restart to switch to another system. At the same time, the system software can be used to back up or restore another system regardless of the system. If it is really unfortunate to get home, both systems can't be started, and can be repaired by WinPE and other tool CDs.

The easiest and easiest way is to install Win7 under XP. It is not too difficult for ordinary users to operate; installing XP under Win7 is relatively difficult, and it is easy to generate many problems, so it is not recommended. Ordinary users install independently; independent multi-system installation, the difficulty is relatively moderate, but the advantages are also quite obvious, more suitable for computer technology enthusiasts to try.
Therefore, for those who have already installed Win7, you can consider re-formatting the system after Win7 system backup. After installing XP, use the backup file to restore and install Win7, which is relatively simple and safe to operate.
