Installing Lenovo Windows 7 upgrade in a new hard disk

[Osasco]

I have an U330 and I have received Lenovo Windows 7 upgrade disc. My pre-installed OS is Windows Vista.

I bought a new 500 Gb hard disk and I want to change my U330's hd for this new one AND also want to install Windows 7 in this new hard disk.

Question: is is possible to install windows 7 using Lenovo Windows 7 upgrade discs directly in this new hard disk?

Or do I need first to change the hard disk (and restore backup or restore factory default) and then upgrade to Windows 7?

Thanks in advance

I dont think it is possible,the upgrade disk will check for a eligible version of Windows vista before starting the installtion
