MacBook won't recognise my new internal harddrive

[akherousia]

Hi there. I am very frustrated because I bought a new internal harddrive (WD 7500BPVT 750 GB 8MB 5400RPM SATA 2.5 Scorpio) and my 2010 model white MacBook won't accept it. Whenever I turn on the machine with the installation disc in it shows the kernel panic.
I upgraded my RAM as well, however macbook works fine with my old harddrive. I tried everything (pushing down the opt. button while booting, pushing down p+r+opt+cmd+power button...) but it doesn't seem to respond.

I would appreciate any help.

Thanks

Is it the installation disc that came with that specific MacBook?
What happens, if you boot from your old HDD and have the new HDD in a USB enclosure for 2.5" S-ATA HDDs and look into Disk Utility?

How to format a new HDD to install Mac OS X onto (or make a bootable copy onto)​

Thanks for the quick reply.

Yes, it came with this MacBook.
I have no idea how to do the USB enclosure thing

I did the Internet Recovery, and then in disc utility I can see the hard drive and I partitioned it before. But when I try to download OS X Lion it says my apple ID has not purchased it which clearly I did. I checked with the apple store and it's under my purchased list.

I appreciate your help again.
