Win7 - 64bit

I have a new PC with a 1TB HDD large. Head there was it only one partition. So I umpartitionert it. C partition and 300GB partition on G (log. LW) the rest. Hiebei stepped unfortunately an error. There was deleted a Conf file and the PC no longer sat up. In the delivery of PCs a WIN7 CD was included and I was trying to repair the system; without success!
Then I reinstalled Windows. Unfortunately, there was not for this CD product key, so that I can use WIN7 only 3 days before the activation is performed. (That would be tomorrow, 6.10.)
So I ordered the new version. (Ordered, at 3:10., Shipped the 4:10., And today at 5.10. Delivered.
Was sent as a postal letter, so no tracking of the package was possible, but it was a lightning delivery. This will require an expensive Morning Express.
Currently I transfer the important files from my old HDD to my new. Especially my scanned slides and negatives. Although these are on my old LW-C under my users, but I come as an admin because ran without problems.
If this is finished, I'll set up Windows.
Maybe I'll format the old HDD (640GB) and new use for backup.
PS: The Product Key is wirlich hard to read as you need a magnifying glass and bright light!

Addendum: Today I installed Win7, went without problems. Also, the product key is accepted. As a language and country setting I chose GERMAN. And it is German!
After installation is complete but a few things were still needed.
There was no network connection
The possible resolution was modest
The sound could be better
But I could remedy, as I have inserted the DVD from the motherboard and then installed. Now everything is as it should be.
Now NIS runs only once completely across both HDDs, then Office and Photoshop is already installed, and that was it.
