XP and Vista installed the same partition

C partition is the outermost circle of the hard disk, the benefits of doing system partition naturally need not say. Install XP and Vista in a partition, you can back up the dual system at the same time, otherwise any system will go wrong, it will affect another system can not start. I found that the XP system installed in this way is almost free of viruses and can be streaking (because the virus authors use fool programming to ensure that the virus files are as small as possible and spread through the Internet, even if the virus enters you The machine can't be used because it can't find the infection path, but it can't be spared by the USB flash drive. As for why the two systems can not be installed in the same partition, it is because the three folders of the two systems have the same name: Documents and Settings Program Files Windows (2000 is WINNT), as long as XP Change the installation directory of the system, for example, under C:\\WINXP\\. Thus, the three folders become: C:\\WINXP\\Documents and Settings C:\\WINXP\\Program Files C:\\WINXP\\Windows. However, the installed system cannot be changed, which means that the XP system CD must be re-created. The entire process requires the following software: CD image editing software UltraISO system CD test software VMware Workstation or Virtual PC CD burning software Nero XP-Vista boot menu modification software VistaBoot PRO 3.1 I sent a vision of XP and Vista in the Vision Forum a few days ago Posts installed in a partition, get the support of the majority of users, and pointed out the shortcomings of the post. In fact, I have complicated to write a very simple post. Now I am going to modify the post. The content is as follows: Insert a CD file of your usual XP into the CD-ROM drive, open UltraISO, execute “file”→“ CD-ROM, find these two files: winnt.sif HIVESFT.INF, should be in the \\i386 directory, if your CD is not the XP system original CD (such as the system CD made with EasyBoot, this system CD with color Background image and Chinese menu), then you have to find the installer startup folder (about 6-9M, often with BOOT EZBOOT as the folder name). Take the winnt.sif in this folder as the standard, extract these two files and save them. Don't turn off UltraISO, because it's going to be used next. Open winnt.sif with Notepad and add the following in the [Unattended] column: TargetPath=\\WINXP\\WINDOWS ProgramFilesDir = "\\WINXP\\Program Files" CommonProgramFilesDir = "\\WINXP\\Program Files\\Common", last Save this. Open HIVESFT.INF with Notepad and find the DEFAULT_PROFILES_DIR="%SystemDrive%\\Documents and Settings" line and change "%SystemDrive%\\Documents and Settings" to "%SystemDrive%\\WINXP\\Documents and Settings", Then save.
