Moving win7 on a secondary disk (T420s)

Dear all,

I just ordered a T420s with a 160Gb SSD + a HD adapter 43N3412 + a
500Gb hard disk.

I am planning to use mostly Linux, and to keep win7 for games. Is
there a standard procedure to erase win7 from the SSD and re-install
it from the recovery disk on the external HD ?

This should of course be possible with a standard win7 install disk
(using an external usb optical drive), but I wonder if the recovery
disk permits so much flexibility or will only accept to put the
computer back in its "original state", that is with win7 on the SSD.

Thanks for any information.
