Install XP on a Vista-pre-installed PC and set dual boot

Today, more and more PCs are pre-installed with Windows Vista at the factory, which is largely convenient for users-though the pre-installed Windows Vista is a simplified version of Home Basic-but for many users, it may be more accustomed to Windows XP, Plus, some of the apps you use on a daily basis may not work well in Windows Vista, so many people want to install Windows XP in a system that doesn't affect Windows Vista pre-installed in the system, which is paid for.

Many users want to know how to install Windows XP on a PC pre-installed with Windows Vista, and set up a dual boot to go to different systems, given our limited energy and inability to respond. So here's a quick summary of the basics of installing Windows XP on a Vista-pre-installed pc in the hope of being helpful to friends.

Warning: Do not install Windows XP directly on a PC preinstalled Windows Vista

As we all know, Microsoft has adopted a new system boot management mechanism in Windows Vista, a new bootloader, unlike the NTLDR used in Windows 2000/xp/2003 since Windows NT, so Installing Windows XP directly on a PC preinstalled Windows Vista will destroy Windows Vista's boot Loader, as we said in the Windows Vista installation tutorial:

If you want to use multiple operating systems in your PC at the same time, you must ensure that Windows Vista is the last installed system, or, for example, if you install Windows XP after Windows Vista is installed, it will cause Windows Vista boot Loader is overwritten by Ntldr+boot.ini, causing Windows Vista to fail to start.

I would like to keep this in mind.

How to install Windows XP on a PC preinstalled with Vista

Here's how to install Windows XP on a PC preinstalled with Vista:

If your PC hard disk has been partitioned multiple partitions at the factory, skip to "Install Windows XP";

Prepare a separate installation partition for Windows XP
In many PCs ' factory settings, hard drives are not partitioned, meaning that the system contains only "C:" disks, especially on most laptops. In this case, you need to split the hard disk first and prepare a separate partition for Windows XP.
