Well, given that the laptop in question has quite a bit of power relative to Windows 2000, and that Windows 2000 will run happily from a mere 128MB of RAM, then I would have thought the path of least resistance is to run it in a virtual machine.
If you only have 1GB of RAM, you may want to invest in a bit more or run Windows 2000 in 256MB. It's an old OS and will handle it.
Virtualbox can be installed and downloaded via synaptic easilly enough. Then point the Virtualbox to your CD drive or use K3b to create an iso image. Depending how how virtualbox goes one or either might be the path of least resistance. Then install as per normal.
Running in a virtual machine is slower than 'for real' but it is less of a headache than frcing a dual boot system, less risk to the laptop and, given this is Windows 2000, likely to run faster than it would have done in tech from 2000-2005.
Also, the virtual box can be fine funed to more closely emulate the tech the OS needs.
There are other virtual machine programs - GMU actually allows direct emulation of specific hardware but I have not had use of it as yet.
I say, go virtual box. I have found it works well as long as there is enough RAM for both the host and 'servant' OS's. Oh, and the chip supports virtualisation. But since the Intel Core 2 Duo T7100 supports virtualisation (Only Atoms do not I believe) then you are in the clear.
