trying to upgrade from win7 to win 8.1. Have iso, but won't accept key

[mjohnson19305]

I have a *.1 key from my 2014 Asus that Win10 killed - literally charred my chip! Now MS  state that it's not recommended to run on older systems and throw their adsat me. Grrr.

I started upgrading to 8.1 using my old iso cd and found my dead Asu's Win 8.1 serieal number. I was still running on WIN 7 and seemed to be upgrading fine after it approved my serial number, but got stuff at 21%. I figured maybe I should have updated it from BIOS, like usual and ended the update after writing down all my serials numbers I might need.

When I got my boot priority pointing to my internal cd drive and restarted, it refused the serial number. Is this for real? Is it because I restarted it?  Is there a work around?

Thank you 🙂

OEM product keys won't work across vendors.

So, if what you are trying to do is activate an OS on an HP PC using a product key you took from an ASUS PC, that is not going to work.

Oh! .. So sorry. By old I meant a 8.1 iso file i copied  from MS that I put on a cd long time ago. The CD runs fine. Just don't understand why it accepted my serial# once, while upgrading running in windows 7, but then didn't when I ran it through the backend. I haven't tried it again runing from the desktop, but might again. Frustrating.
