How to Reinstall Windows 7- with " Partitian "?

Hi folks.

Have you ever seen that movie " Vegas Vacation "? You know, when Chevy Chase was gambling and he never wins?

Its so funny because it is the same sequence of follies as to my computer hell today. I'll just get to the point and hopefully someone can help.

I want to re-install Windows 7 64 bit.( because of Cyberlink 8 and various files by multiple users being locked, which are separate issues). I have the disc and legit activation key.

I have a 1 TB hard drive right now. Out of all the programs and files, I simply want to save a few 200 gigs of videos that I have edited. However, I am unable to move them to my WD external drive ( another separate issue, LOL ) because Windows 7 does not recognize it nor WD have a driver for it.

Anyway, can I backup those completed files on a part of internal hard safely, and then perform a clean reinstall Windows 7 on the same drive? I've tried with the backup option but can't figure out how to do it. The box only give me options to save on my disc drives. In addition, I must be absolutely certain my 200 gigs of video will be safe.

Again, the Win 7 must be a clean install. I want to BLOW UP EVERYTHING that is left except for my 200 gigs of video.

Thank you in advance for your help.

PS- I am trying to transfer by wireless on my home network to my laptop. Estimated time, 3 days. LOL

200GB... that's a lot of DVDs
Is it a desktop or a laptop? If it's a desktop you could just put in an additional harddisk (they aren't that expensive nowadays) and move your videos there.

How many partitions do you have on this disk? It'll help if you post a screenshot of the disk management window.

If you have more than one partition, just move the files you want to save to another partition- that is a partition other than the one on which you plan to clean install windows.

If you have just one large partition, you'll need to shrink it, then create a new partition out of that reclaimed space. These tutorials tells you how.

Partition or Volume - Shrink

Partition or Volume - Create New

Once you have created a new partition, move your videos over, then clean install windows.

Make sure to remove any encryption you may have set on these files before installing windows, otherwise reading them may be troublesome.
