How to change computer but retain hard disk
What would happen if I take my hard drive out of my current PC and put it in a new PC?
I had to buy a desktop since my laptop died because of a glass of wine. I want to boot from my laptop's Windows 7 in my new machine (every piece of hardware is different but it's still intel/ati), how can I manage that?
Today, WIndows 7 is crashing at the very beginning of it's loading. I've read about Sysprep.exe (http://www.sevenforums.com/tutorials/135077-windows-7-installation-transfer-new-computer.html) and I wonder if I still do that even if my system doesn't boot or if there is a similar bootable tool?
I can't reinstall from scratch because I haven't note the Win7 product key and I'm not able to find it using ProduKey.
