Replacing HDD, reinstalling Win 7 in Toshiba laptop

[fussybritches]

New to this, so seeking guidance. Help appreciated.

The hard drive crashed; I'd like to replace it and install Win 7.

The drive's a Toshiba HDD2L01, a 2.5-inch SATA; 750 GB, 5400 RPM.

First question: Is it as simple as replacing the HD, booting up and installing Win 7?

Second question: If it is that simple, can I safely use a different 2.5-inch SATA (e.g. 1 TB, 7200 RPM)?

Thanks.

P.S. The old HD crashed, and no backup, so it'll be a fresh Win 7 installation; "reinstalling" in the headline should've been "installing."

I decided to go ahead and order. Hope I don't destroy the laptop in the attempt to fix it.
