Hardrive Issue!!!

[SpeedyJake]

I recently brought a new internal hardrive. It's a Western Digital 500GB Scorpio Black 2.5" Sata 3gb and my model number is: WD5000BPKT. I used Time Machine to back up all my data on a external disk, It went all well. So I took my Macbook's (Aluminum Late 2008) battery shield thing off the bottom of the Mac, took the my old hardrive out and put my new one in, it went pretty well I followed all the instructions on the Youtube video (I'll put the link at the bottom of the thread for the Youtube Video). So then I was unsure what to do next so I put the osx snow leopard disk in while booting my new hardrive up on my mac and it comes up with the usual loading screen the blank white background, It made the usual noise when a disk starts to load up but then after waiting a while a icon came up on the blank white screen it was a folder icon but it had a question mark in the middle of it and kept flashing (I'll put the link at the bottom for the picture of this icon). I'm not sure what this means, does it mean that my hardrive is broken or is it no in properly I'm very confused. I followed the instructions on the gizmodo webpage to reinstall my data on my new hardrive (i shall post that link at the bottom of the thread too) but so far it doesn't seem to work.
So could any of you guys help with this problem It's really bugging me!!!
Any help would great guys!

It does that if it can't find anything to boot off of. Make sure the snow leopard disk is clean, then hold C while booting up. That should get you onto the disk. Restore from time machine via the utilities menu.
