Does a clean Windows 8.1 installation depend on hardware installed?

I'm new to the forum although I have been reading it for quite a while, so, hi to everyone!

I will first explain why I'm asking this, I'm currently installing windows 8.1 through a virtual machine into a secondary HDD I've connected (See rawdisk and this for more info on how to do that). I've done it a couple of times, so no problems with that.
The reason for this is so I can still be using my pc while installing windows (or other OS) into a secondary HDD or partition.

But while I usually do this for my own PC, this is for my brother's PC. That's why I want to know if when I'm to give him this HDD with pre-installed windows 8.1 he will have problems with the OS being configured for another hardware (being it 64bit compatible, taking into account Windows 8.1 license problems when changing hardware and not installing any driver apart from running windows update).

From my own experience, because virtualbox emulates hardware it wont be any different than what I usually do. But I'm not so sure about the processor, because that's not emulated in virtualbox.

In short: Can a HDD with windows 8.1 freshly installed be transferred to a new pc without any incompatibilities or optimization problems( setting aside 64 bit incompatibilities)? Is the kernel in anyway optimized to the processor it was installed with? (Like in linux where you can do so).

PD: I'm not a native english speaker, if you see any error please highlight it so I can fix it! Thank you :)

For me i tried before
u cannot transfer a hard disk directly to another computer (window key and motherboard spec etc not the same ) it will not run Even it is pre-installed , the data inside still belong to the original pc , won't work unless reinstall

(ps internal HDD only never tried external HDD )

sure ! it depends on the processor (sure) or motherboard (not sure) and most importantly HDD writing and reading speed
when u run the virtualbox surely will lag a bit (eat up some cpu processing power)

Hi, thanks for the answer!
I agree with you, the performance will be different for sure if I change the processor and/or HDD.
I see now that I may have phrased my question incorrectly, will edit it to address the issue.
What I meant to say is if the HDD with the OS pre-installed can be transferred to a new PC without the change in hardware resulting in an unoptimized or even incompatible system (leaving aside 64/32 bit compatibility).

Hope I'm clear enough now! :)
