upgrade question ?

hey all ! just wanted to know whats the easiest way of going about this....
just got a new 250gb hard drive 2x 1gb ram and a copy of leopard (treated myself !! ) for my macbook 2ghz core duo macbook.
I am familiar on how to install all the hardware thats no problem but..
can i just install hard drive and then use my restore discs to install tiger?
not bothered about loosing files.. then uprade to leopard?
am a newbie with the mac thing so maybe someone could steer me in the easiest way to have all hardware installed with leopard as my os ?

thank you in advance
andrew

Why don't you install directly from the Leopard disc? Is it an upgrade disc you bought?

I'd just try it and see which one works, no harm can be done .. if Leopard direct doesn't work then try as you suggested
