This is what I get when I try to install W10.
Unlimited Primaries, I created the partition in partition work, set it up in boot edit and booted to it to write it to the MBR. I chose BIOS Sequence and rebooted. W10 setup starts and when it gets to the select partition screen, the W10 partition is the only one that shows and is labeled System, but when I select it, I get the error. Looked through the KB with no joy. What am I missing? I've installed before with no issue so I don't get what the problem could be.
