Windows 7: Backup unbootable Windows 7 to another partition

Backup unbootable Windows 7 to another partition

Windows 7 Home Premium won't boot on my Vaio laptop even in safe mode (stuck at classpnp.sys, then it goes to a BSOD and I'm forced to restart). I tried many solutions but none of them worked.
After that I decided to boot from an USB with Ultimate Boot CD installed and ran every hardware test with positive results. Then I booted Parted Magic and it was able to mount the hard drive (even the system and recovery partition). From there I could just copy the files that I wish to keep to my external USB flash drive and make a clean Windows 7 install. The problem is that the transfer rate is painfully slow and I have a lot of pictures.

I read that Windows creates a 'windows.old' folder when doing a custom install containing the old installation Program Files and Users folders. I don't trust that since Windows can't even boot in safe mode. Are my suspicions right?

The other option is to create a new partition with Parted Magic and dump all the files there, but if I do that the Windows installation program won't create a separate System partition (around 100 mb) and I read that it's convenient to do that instead of having Windows in only one for security reasons.

So my question is: is it worth taking a long time transferring files to my other laptop for the sake of having Windows in two partitions? or should I just save time and use a new partition for backup? even better, is it possible to install Windows System in a separate partition when the hard drive already has an existing partition that I wish to keep?

I found this tutorial:
System Reserved : Create Using Disk Management

but I find it a tad confusing. From my understanding I could just create the system partition later following the steps in 'Option One' only. If so how would Windows know about that? is it because of the 'system reserved' volume label? I mean, aren't you just creating a generic partition with the label System Reserved there?

The VAIO recovery partition seems to be corrupted so I discarded that alternative. I also forgot to mention that I am able to run the Windows command prompt in the recovery environment but I don't know if there are any tools there that could be useful.
