I need to reinstall Windows 7 but I don't have the original disk that goes with the machine I do however have a different Windows 7 disk. My question is would I be able to install Windows 7 using this separate disk? I have a licence key for Windows 7 which I can use but I'm wondering if each Windows 7 disk is tied to a specific licence key?

You shouldn't have problems activating with a generic retail disc, else you can always call the automated MS activation hotline. – Karan Jul 12 '13 at 0:23

some windows 7 disks work, but some have issues activating. I used a dell disk on a compaq machine and i couldn't activate windows :(

i'm assuming they are manufacturer specific?

if so i believe you can download a generic windows 7: (home premium x86) (home premium x64) (PRO x86) (PRO x64)

burn the right iso to a dvd and boot from it.

I could be wrong, but I believe the Microsoft license agreement requires you to obtain replacement OEM disk(s) from the vendor...Unfortunately, all OEM media isn't created equal.
