change from Vista to Windows 7

[imoldtx]

I was not sure where to ask this question.
I just replaced the hard drive in my daughter's laptop and reloaded windows 7 using the disk that came with the computer.
I have another laptop that has a side by side configuration problem. I tried to correct that problem using all of the suggestions on the Vista forum BUT since it will not allow me to get on the internet, I can't download anything that may help.

SO, my question is: If I back up the hard drive and wipe it can I install (replace) windows 7, using the disk that came with the other laptop, in place of Vista?

you would still need to purchase a license. but theoretically yes. wait for more answers before going ahead.
