Installing Windows with a key that is different from the one that is sewn into the laptop's BIOS, who has come across?

Question

Windows

I have a laptop with licensed Windows 8.1 x64. The key is in the bios. But the Windows version is single language. And virtualization is disabled in it, although the percentage supports it. I want to buy with the release of 10 pro version, since virtualization is needed for work.
The question is whether I can normally activate Windows with a new key and how the process of reinstalling Windows should go: will I need to install the Windows under which the license is in the BIOS and then upgrade to the one I buy or can I immediately install 10 pro and just enter the key? won't it be a problem?
Googled. Didn't find anything clear.

Answer 1

tech support said that if you buy a system upgrade, you will have to install the one under which the original key, then upgrade.
if you buy a full-fledged Windows and enter it during installation, it will accept this one, and the one in the BIOS will ignore it.
I'll try it soon and write back.

To avoid problems, you need to take and remove the image of the laptop disk before experimenting, create a bootable USB flash drive with the image recovery environment, make sure that you can boot from it, and then experiment.
Even if you "know for sure" that everything should work out, this does not prevent you from doing it.
And so, from experience, there will be no problems with installing and entering the key of the purchased Windows. I did it myself, and more than once. But more than once I came across a situation where completely harmless actions (for example, "Reset" (which is essentially a factory reset) of eight - led to a bootlap) led to problems that, if there was a backup, were solved quickly and easily. Laptops, they are, all with a temper.

Not all vendors provide a free upgrade to the next version of the system. If your vendor provides such an opportunity, then reinstallation is not needed, a regular update should pass without problems. Most likely the old key will not work.
Well, then you know the procedure, mhdd is there ....
