and on that I didn't see any program for determining make, model of motherboard. When you boot up, perhaps it's displayed on the splash screen. If this is a big computer maker like Dell, HP, then should be a tag saying what it is. Reason that needs to be known is because some have restore partitions in differing areas and you can be given more accurately aimed guidance.
I've used Knoppix in past for emergency use, but there are really better Linux systems out there today, and on LIVE DVD, if you have DVD drive instead of just a CDROM drive. If you can burn your own DVD, then I'd suggest some type of Mint, or Kubuntu, or Zorin.

Least expensive DVD's for order of good quality and they contribute back to the developers is
I personally use Linux Mint 17 MATE version, with Kubuntu as a backup. Kubuntu is a very visually pleasing system, very developed, just more than I need for what I do, so I prefer the simpler Mint MATE most of the time. If someone likes both, then Mint KDE is a good compromise between them. Unlike Knoppix which is more a rescue disc, both the Mints and the various Ubuntu's are devoted to full desktop usage, with more information gathering helps than I saw on my old Knoppix 6.2 disk, don't know in comparison to the newest Knoppix however. I do know Mint 13 which was out at same time as Knoppix 6.2 was a more robust operating system. Knoppix was a ground breaking system years ago when it began the first "LIVE" CD's, then came the more robust LIVE DVD's, but in the past few years it's lagged behind some of the more popular ones. On distrowatch it rates below 33+ other Linux versions now, while the Ubuntus, Mint (#1), and Zorin are all in the top 10 preferred systems.
As for your windows system, do you have restore DVD or CD's for it? When you bought the system did it suggest burning backup of the system? You may end up needing to do a full restore. If so, then in that case, you would need to first backup your personal data files using the Linux to another drive, or burn to DVD's depending on how much data you have, before doing a full restore on of the W7.
