Situation: A pc bought from Dell had two hard disks in raid. The hard disks broke down and we replaced them with one disk (not in RAID). (we bought the disk ourselves because the dell pc was just one month out of warrenty).
Next we had to do a clean install of Windows 7 32bit, but here is the problem: we used a regular Windows 7 32bit cd for the installation from another pc. We entered the serial key from that Microsoft sticker that was on top of the Dell pc, just below the Dell service tag. Everything works.
Now suddenly we receive a message on that pc that Windows activation is not valid. We had contact via mail with Dell support and they told us we had to install Windows with the Dell-CD/DVD that was included. (sounds stupid, but we forgot that there was such a CD provided.)
We have the Dell cd here now and but we don't want to format the PC again and install everything. Is there a way to activate Windows 7 now with that Dell-CD/DVD ? If so, what are the necessary steps to do this?
Thanks in advance.
