Hard Drive Swap?

[qurious]

Some time ago I replaced an IDE hard drive with Windows 8 installed for an SSD drive onto which I installed Windows 7. I would like to know if I can temporarily swap back to the IDE drive (Windows 8) while I obtain the Windows Product Key (embedded in BIOS apparently) and then replace the SSD drive (Windows 7), or boot from an external docking station and if so how do I do that?


I am totally confused about the BIOS. Does a different OS change the BIOS details? Any help will be greatly appreciated.

Yes, you can switch it back and it should boot up no problem.

I`m no windows 8 expert, but there`s no key embedded in the bios. It`s in the operating system, and unless it`s a retail key, it`s useless to you on another computer.
