Can you install windows 7 using a Recovery disk from another computer?

That will depend on how the recovery disc is structured. If it uses the manufacturer's own imaging program to create the system on the disk, it will likely not work with another computer. If it uses the usual Windows installer, it should work.

Regardless of whether you can install Windows from the disc, it will usually not be activated and you will have to purchase another license key to use it on that computer.
