Imac doesn't start up MAC OS X after replacing a new Hard disk

Hello,my imac's hard disk was broken. I changed it with a new exactly same type and brand hard disk. After chancing, I tried to format it with mac format dvd, but I couldn't it. When I started the imac, it stuck on apple logo and after 5 minutes shows the folder with question mark. I purchased external enclosure. I formatted a new hard disk with using external enclosure. I mount new hard disk to imac. It still doesn't start up. When I put a new hard disk into enclosure to connect another imac, it shows up. I don't understand what the problem is.

Thanks

iMac, Mac OS X (10.6.8)

Whe you say "Mac Format" DVD do you refer to the original DVD set that came with the iMac?

Is it Disk Utility you are using to attempt the Partition and format of the new HDD while fitted inside the iMac?

You could have damaged the data cable inside the iMac while changing the drive.

yeap it is original Mac Format DVD.

yes I used Disk Utility to attempt the partition and format of the new HDD

When I mount back old HDD, it still works but it is very slow working. The problem should not be about the data cable.

PS: the old HDD is not completetly broken, it works but it is very slow working.

I got my old HDD back up with using time machine, I tried to format using time machine. When starting up imac, I press option key, it doens't show up anything, it stuck on apple logo.

Thanks
