In my searching so far, I've gotten inconclusive answers to this question. It seems to depend on the person's views on how the MS Licensing works, or to what degree they feel bending the rules is "okay." All I want to know is what the real answer is to the letter of the law.
I have a PC I am replacing the primary HD with a SSD. The user wants me to load Win7 on the SSD and make that the primary boot and workspace. He uses a crappy application that doesn't play well with anything else, so he's asked me to use the old HD and load Win7 on that as well. Same license key. That way he can run that app on a "clean" install of Win7 without anything else getting in the way.
What's the simplest/best way to load and boot to Win7 on two drives on the same PC?
Can I use the same key to install Win7 on both drives of the same PC? I don't think you can without buying a second license. But confirmation appreciated.
