HDD problems iMac 20"

[Godrax]

Heres the thing:
Recently bought an iMac.
Ran perfect for first days.
I installed Snow Leopard and Windows 7 trough boot camp but then the problems started.
If I boot up OSX it takes like 5 minutes and a loading bar appears.
If I boot via OSX Leopard DVD and use Disc Utility it only reconizes the whole HDD (with wrong amount of GB) but no partitions.
In OSX it reconizes my partitions.
If I do a verify disc it says that I need to repair my disc, which is impossible cause it doesnt reconize when I boot with Leopard DVD.
Anyone got an idea what I should do?

Thanks,
Thomas

Do a clean install of Snow Leopard. Boot from the DVD and select Disk Utility and wipe the whole HD. Then install OS X. You can contact Apple if you want but try above first

Call Apple and get it fixed. There's nothing you can do now.
