Did exactly this. Still not activated. Produkey tool shows 2 keys. One generic Retail 10 pro key and another my BIOS OEM key ( the 8 core one )
Ah ha! I believe thats the ticket. If an activation with home was done successfully then yes, Pro most likely will not install because of the HWID and Home install.
It could be that the activation servers are not online. I've heard from a few ppl that they were offline from time to time.
Surely MS wouldn't block any upgrades from home to pro for the same machine, if the machine was 'genuinely' activated with a 7 or 8.1 Pro equivalent first
but Home was first, then going to pro after 10 was installed might have a play, but your thought has plenty of merit. Curious stuff we are into sometimes. KMS seems like the solution until another can be achieved though.
Ok. So I should wait! Don't know why it says product key blocked. Shouldn't it say unable to connect or something ? PS:- Any way to delete the BIOS OEM key?
Not sure why it would say blocked either. Unable to connect would be a better explanation to why it cannot.
Download an generic BIOS from the Machines Manufacturer, means a BIOS for an computer without any pre-installed OS! Save your old BIOS with an BIOS Tool and install the generic one. That would give also an new HWID!!
It will always show the pro generic key. That's the default. It's probably giving errors because it's trying to CHANGE to the home key to activate. Can you try to re-install 7 pro/ult sp1 again and make sure network drivers are enabled and system is online and do the winloader and upgrade again? If it couldn't connect to internet before upgrade it wouldn't activate post-upgrade. We've already tested that.
Some PCBETA member newly installed with multiple-editions, it automatically installed Windows 10 Core and activated with its Windows 8 Core OEM DM key. Other editions? Failed in both upgrade and newly insallation. Unless, I think, you can manage what you said: PS:- Any way to delete the BIOS OEM key?
