1. Insert the engraved Windows 7 installation CD (or use a virtual drive to load Windows7 image).
2. Click "Start" - "Run", and the command line window will pop up.
3. Type X:\\boot\\bootsect.exe /nt52 all /force in the command line window and press Enter. (Note: X:\\ represents your CD-ROM drive letter, or a virtual CD-ROM drive letter. For example, if the DVD drive letter is F, type F:\\boot\\bootsect.exe /nt52 ALL /force.)
4. Pop up the Windows 7 installation CD (or uninstall the ISO image file in the virtual drive).
5. Restart your computer.
The computer will boot with a previous version of Windows installed. The startup items of Windows 7 system are gone, and EarlyVersionwindows is gone. Only the startup items of Windows XP 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 Windows 7 is located, saving time and trouble.
