Hello, I'm not sure of the cause of your installation problem, but I did see firmware errors in the logs, as well as the windows filesystem wasn't cleanly unmounted. It might be worth installing BIOS updates from Acer, if any are available, and perhaps also using a 'restart' with windows, and not letting it get past the bios. (Windows 'shutdown' apparently isn't an actual shutdown these days.)
I hope this helps.
