Lenovo Ideapad Yoga 13 running 8.0.

I was having trouble getting "Get Windows 10" to appear in the taskbar, and after trying all the fixes I could find online I did a factory reset. I got Windows Update going and it downloaded ~150 updates. It did not, however, update to 8.1. After hours of attempting fixes, I still can't get this update. I've tried the troubleshooter, directly downloading and installing it myself (not compatible with my system), I've tried going to Windows Store but it fails without a specific error, only "the app wasn't installed -- view details." Even tried a virus scan in Safe Mode, but Avast wouldn't do it in Safe Mode, so I just ran it in the regular environment and it was negative.

Any ideas? Thanks in advance.
