Reinstalling Windows 7 from a laptop

[01philip01]

Hello! I just installed a new mx100 256gb ssd into my asus k53sv-dh51 laptop, im planning to move the original hdd into the optical drive bay when I finally get the caddy n the mail. In the mean time I want to reinstall windows 7 onto the ssd, I used the following forum thread http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/page-2#post-124821 in the past to get window 7 iso's for my thinkpad and desktop where they worked fine but the link for the windows 7 home preimum seems to be dead and redirect to a microsoft error page. http://microsofthup.com/hupus/error404.html then directed to microsoft's own website which never happened before? http://www.microsoft.com/en-us/software-recovery

I entered my key and it just said it was already redeemed and to contact the manufacturer.
Should I just get the iso from the first page? http://www.w7forums.com/threads/official-windows-7-sp1-iso-image-downloads.12325/
or this other random one that was under similar threads http://www.w7forums.com/threads/windows-7-iso-–-official-direct-download-links.2910/

Have you paid for a copy of Windows 7 and downloaded it onto usb?

The cdkey is the oem key that came with the laptop, I'm just trying to reinstall it. It didn't come with anything but I did make backup cd's of the fresh computer when I first got it which are now lost and without labels.

To reclarify, I'm asking which isos to use for the windows 7 home preimum 64bit install.
