So, this SP3 has a Linux OS on it. I want to install 8.1 or 10. I went to the download page for the Surface and entered it's SN and downloaded both packages for 8.1 and 10. However, neither will install. The W10 version seems the most promising as one option was to reinstall from the Cloud, which says it will wipe the disk and download the OS from the cloud. But it immediately goes back to the previous section. None of the other options work. For this reason I just took a copy of 8.1. But it says, no you have to use the recovery installation. So, it's like a Catch22. Any suggestions?
