Which win7loader it is. Check slic and certificate status using vista7 slic ldr or SLIC dump tookit. Then one can answer your problem.
You need to check whether the loader has been successfully removed. Reboot and check windows activation status in cpl>system>scroll to bottom. It should be unactivated. Then make sure that you have SLIC2.1 in your bios using the SLIC Dump toolkit. The SLIC brand must match the cert. Install the cert using the command slmgr -ilc <path to cert> in the command prompt (Run as admin). Wait till it says successfully installed. Then install the correct OEM key with the command slmgr -ipk <key> again in the command prompt as admin. Wait till it says successfully installed. If everything goes well, your system should be activated now.
