Windows 7 - problem with w7 after copying it to other hdd

I recently bought a new pc and gave my old to my dad,he installed his hdd in this pc and ofc the xp pro didnt work.We installed windows 7 on that hdd and it worked fine.Later he wanted to add a new xp to that HDD,when we did that the dualboot showed the old and new xp pro and the Windows 7 was now in a logical partition,so not bootable anymore. So i used partitionmaster to copy it to a primary partition on a second HDD.After running the repairtool from the Windows 7 disk it was running fine again.The logical partition on the first HDD with Windows 7 on it was full, so he wanted to format that one.After formatting it and deleting the partition the windows 7 on the second HDD didnt work anymore.It starts up and than says its building the desktop.after ctr alt delete there is a menum to choose from ,with change user,taskmanager etc.If i click taskmanager there is a message saying that it is an illegal copy,withch is not true ofc.Is there a solution to solve this problem?

Reformat both HD's, & use this tutorial:

Thanks for the replys ,i surely ask first next time when i try something.But how is it possible that when i delete the Windows 7 in the logical partition on HDD1, the exact copy from that partition on a primary active partition on the second HDD doesnt work after that deletion?Is it missing a path to the keycode?And if so can i recreate that path?

Easy way or Hard way.

Easy way clean install.
