Installed win7 on a OEM win8 machine... kms says invaild microsoft volume license
I came across this on the final hour of the last day of term, so i haven't really dug too deep into it yet. however i'm back on monday so i thought id start to reseach.
we have a microsoft volume license which allows use to install the OSs as long as the machine has a current OEM/retail license already. (as per t&cs).
we have a batch of OEM/retail DELLs that came with Win7 HP. we've nuked these and imaged them with the in house image. no probs kms says hellow and welcome etc etc.
We also have some IBM Win8 pro machines. i set the first one up on FOG and all went well.... image works etc etc.... however, we get a KMS microsoft volume license screen pop that says something along the line of;
......Invaild microsoft volume license make sure your have a OEM/Retail version of windows before activing with KMS. If not try using a MAK or retail serial key...
Any ideas? the machine dont have a WIN8 oem serial on the them.... i assume its something embedded in BIOS?
