Easily remove Windows 7

under dual system With the release of Windows 7, many users have used this new operating system, and most of them have dual systems. Building a dual system is very simple, so how to uninstall Windows 7 under dual systems is difficult for many users. Below are the tips we have compiled, and I hope that it will be helpful for users who need to uninstall Windows 7.
1. Insert the engraved Windows 7 installation CD (or load the Windows 7 image with a virtual CD-ROM drive).
2. Click "Start"-"Run" to bring up the command line window.
3. Enter X:bootbootsect.exe /nt52 all /force in the command line window and press Enter. (Note: X: represents your CD-ROM drive letter, or virtual drive letter. For example, if the DVD drive letter If F, type F:bootbootsect.exe /nt52 ALL /force.)
4. Pop up the Windows 7 installation CD (or uninstall the ISO image file in the virtual CD-ROM drive).
5. Restart your computer and the computer will boot with the previous version of Windows installed. The startup items of the Windows 7 system are gone, the Early Version windows are gone, and only the Windows xp startup items are left, which is basically successful.
6. Manually delete Windows 7 files and folders, such as program files, users, and Windows folders. Or if there are no other important files, you can directly format the partition where Windows7 is located, saving time and trouble.
