Maybe someone could help if you give the make and model.
The Chinese bit is a problem...
Have you tried putting your XP disc in and trying to find the drive in "computer", and running setup.exe from the files on the Windows disc. If you find "computer" in Vistas start menu the drive will show there. Just right click it to explore and run the files.
Computer normally 6th up from bottom in the list,
If that doesn't work perhaps changing the boot order in the bios to boot from CD and then the Windows disc should load.
