Hello.. I have a batch of Acer Aspire 10 tablets that came pre-installed with Windows 8.1. I need to upgrade these to 8.1 Pro so that I can attach them to my domain.
I have a Volume Licensing Agreement that allows me to upgrade all my OS's, but I cannot quite figure out how to make it work with these tablets.. All efforts to upgrade them with the .iso from the VLSC have failed. I have NOT deleted any partitions or tried a fresh install.
I am assuming the issue probably lies with the OEM License key embedded in the Bios.
I have tried an in-place upgrade with my GVLK (I use a kms server). but have tried the mak as well. I have tried running the upgrade from the CD (form boot and the OS and from a mounted ISO. When running from the OS, it seems to go through the entire process, but at the very end it sets everything back.
My license and the software assurance should allow me to do this, but I am at a loss. Any help would be greatly appreciated..
