Hey, could you please teach me how to remove windows 8 preview? i formatted the W8 operating system disk, but whenever i turn on my laptop, there always be a windows boot manager to ask me to choose the operating system between preview and vista: ( please help

I think that which you are asking can be done with simple 4 steps:

Backup files from Windows 8 (on USB stick / external HDD)
Shutdown Windows 8
Put the other Windows installation CD and load it
Follow the installation instruction. Make sure to format the drive (partition) where you can installed the Windows 8

Hope this helps.

Boot into Vista. Install EasyBCD. Fix the MBR. Easy

Boot into Vista.
> Disc Management
Delete the drive/partition holding Windows8
Format that drive/partition
> msconfig > Boot tab
Delete or Remove the Windows8 path.
